Definitions
- the invention relates to automotive fuel pump modules, and more particularly to the design and installation of automotive fuel pump modules.
- a typical fuel pump module may include, for example, a fuel pump, a fuel reservoir, a fuel level sensor, one or more suction filters positioned upstream of the pump inlet, an in-line fuel filter positioned downstream of the pump outlet, and a pressure regulator.
- the fuel pump module usually rests in the bottom of the tank and will pump fuel from the tank until the tank is substantially empty.
- Attached to the typical fuel pump module is a flange that closes the opening after the fuel pump module is installed in the tank. Fuel exits from, and can also return to the fuel tank through ports formed in the flange.
- the size and shape of a fuel tank is dictated by the available space under the vehicle body. While it has long been known to install the fuel tank adjacent to the rear of the vehicle, it has recently become more common to move the tank forward and install it under the back seat of the passenger compartment. Due to the space constraints associated with placing the tank under the back seat, the height of the tank must be reduced. The available setup height for the fuel pump module used in this low-profile tank is greatly reduced.
- the in-line fuel filter communicates with the fuel pump outlet and filters particles from the fuel that could hinder the operation of the fuel injectors. Particularly, the in-line filter removes particles or debris that may have passed through the suction filter or that may have been deposited in the fuel as it was pumped through the fuel pump.
- the in-line fuel filter is typically housed within the cylindrical reservoir and should be large enough to function effectively for the life of the vehicle. For larger vehicles and high performance vehicles with high fuel consumption, larger in-line filters are necessary. Unfortunately, it is becoming difficult or impossible to fit the large in-line fuel filters into the smaller fuel pump modules.
- the present invention overcomes this problem by providing a fuel pump module having an in-line fuel filter coupled thereto in such a way as to permit installation of the fuel pump module into a low-profile, small-opening fuel tank. Because of the improved method of coupling the in-line filter to the remainder of the fuel pump module, no sacrifices need to be made with regard to the size of the in-line fuel filter. Installation of the fuel pump module remains simple and no extra tools are necessary.
- the invention provides a fuel pump module including a fuel reservoir, a fuel pump communicating with the fuel reservoir and having a fuel outlet, and a fuel filter assembly movably coupled to the fuel reservoir to facilitate installation of the fuel pump module into a fuel tank.
- the fuel filter assembly communicates with the fuel outlet to filter fuel that has passed through the fuel pump.
- the fuel filter assembly is pivotally movable with respect to the reservoir.
- the fuel filter assembly is linearly movable with respect to the reservoir.
- the invention also provides a method of installing a fuel pump module in a fuel tank having an opening, the fuel pump module having a reservoir and a fuel filter assembly movably coupled to the reservoir.
- the method includes positioning the fuel filter assembly in a first position relative to the reservoir, inserting the fuel filter assembly into the fuel tank through the opening, inserting the reservoir into the fuel tank through the opening, and moving the fuel filter assembly with respect to the reservoir to a second position, thereby allowing the reservoir to be fully inserted into the fuel tank.
- moving the fuel filter assembly to the second position includes pivoting the fuel filter assembly with respect to the reservoir.
- moving the fuel filter assembly to the second position includes moving the fuel filter assembly linearly with respect to the reservoir.

- the components of the in-line fuel filter assembly 102 can be manufactured and assembled in any suitable fashion.
- the housing 106 , the extension member 118 , the fuel inlet 110 , and the fuel outlet 114 can be a single injection molded part capable of receiving and housing the filter media.
- the extension member 118 can be mounted in any suitable manner to a pre-existing in-line fuel filter.
- a flexible inlet conduit 130 is connected between the fuel pump outlet 66 and the fuel inlet 110 to provide communication between the fuel pump 58 and the in-line fuel filter assembly 102 .
- a flexible outlet conduit 134 is connected between the fuel outlet 114 and the flange outlet port 94 to provide communication between the in-line fuel filter assembly 102 and the external portion of the fuel system.
- Fuel exiting the fuel pump 58 enters the in-line fuel filter assembly 102 where it is filtered to remove any debris present.

Description
- The invention relates to automotive fuel pump modules, and more particularly to the design and installation of automotive fuel pump modules.
- The use of fuel pump modules to pump fuel from fuel tanks is well known in the automotive industry. A typical fuel pump module may include, for example, a fuel pump, a fuel reservoir, a fuel level sensor, one or more suction filters positioned upstream of the pump inlet, an in-line fuel filter positioned downstream of the pump outlet, and a pressure regulator. The fuel pump module usually rests in the bottom of the tank and will pump fuel from the tank until the tank is substantially empty.
- Installation of the fuel pump module into the fuel tank is made possible by an opening or hole in the tank that provides access to the inside of the tank. The opening is normally formed in the top wall of the tank and is normally circular. All of the components of the fuel pump module must be packaged together to fit into the tank through the opening. It is often the case that the components are packaged within and below the substantially cylindrically-shaped reservoir such that the entire fuel pump module is no larger than a cylindrical envelope defined by the diameter of the opening and the height of the tank. Alternatively, some prior art fuel pump modules include an elongated suction filter that protrudes radially outwardly from the bottom of the reservoir. Due to the relatively flat and elongated shape of these suction filters, they can be inserted into the opening prior to insertion of the remainder of the fuel pump module without posing serious installation problems.
- Attached to the typical fuel pump module is a flange that closes the opening after the fuel pump module is installed in the tank. Fuel exits from, and can also return to the fuel tank through ports formed in the flange.
- The size and shape of a fuel tank is dictated by the available space under the vehicle body. While it has long been known to install the fuel tank adjacent to the rear of the vehicle, it has recently become more common to move the tank forward and install it under the back seat of the passenger compartment. Due to the space constraints associated with placing the tank under the back seat, the height of the tank must be reduced. The available setup height for the fuel pump module used in this low-profile tank is greatly reduced.
- In addition to setup height reduction, fuel pump module manufacturers are also having to adapt to reductions in the size of the installation opening in the fuel tank. Recent regulations governing hydrocarbon evaporation and emission have forced fuel tank manufacturers to minimize the size of the opening, with some openings now being as small as four inches in diameter. The combination of reduced tank height and reduced tank opening size has posed problems for manufacturers of fuel pump modules. Simply stated, it is becoming difficult to package all of the necessary fuel pump module components in an envelope capable of being installed in the low-profile, small-opening tanks.
- One of the major obstacles to overcome is the size and location of the in-line fuel filter in the fuel pump module. The in-line fuel filter communicates with the fuel pump outlet and filters particles from the fuel that could hinder the operation of the fuel injectors. Particularly, the in-line filter removes particles or debris that may have passed through the suction filter or that may have been deposited in the fuel as it was pumped through the fuel pump.
- Unlike the suction filter, which can be a relatively thin member just outside the intake of the fuel pump, or alternatively can project radially outwardly from the bottom of the fuel pump so as not to utilize any significant portion of the available setup height, the in-line fuel filter is typically housed within the cylindrical reservoir and should be large enough to function effectively for the life of the vehicle. For larger vehicles and high performance vehicles with high fuel consumption, larger in-line filters are necessary. Unfortunately, it is becoming difficult or impossible to fit the large in-line fuel filters into the smaller fuel pump modules.
- The present invention overcomes this problem by providing a fuel pump module having an in-line fuel filter coupled thereto in such a way as to permit installation of the fuel pump module into a low-profile, small-opening fuel tank. Because of the improved method of coupling the in-line filter to the remainder of the fuel pump module, no sacrifices need to be made with regard to the size of the in-line fuel filter. Installation of the fuel pump module remains simple and no extra tools are necessary.
- More specifically, the invention provides a fuel pump module including a fuel reservoir, a fuel pump communicating with the fuel reservoir and having a fuel outlet, and a fuel filter assembly movably coupled to the fuel reservoir to facilitate installation of the fuel pump module into a fuel tank. The fuel filter assembly communicates with the fuel outlet to filter fuel that has passed through the fuel pump. In one aspect of the invention, the fuel filter assembly is pivotally movable with respect to the reservoir. In another aspect of the invention, the fuel filter assembly is linearly movable with respect to the reservoir.
- The invention also provides a method of installing a fuel pump module in a fuel tank having an opening, the fuel pump module having a reservoir and a fuel filter assembly movably coupled to the reservoir. The method includes positioning the fuel filter assembly in a first position relative to the reservoir, inserting the fuel filter assembly into the fuel tank through the opening, inserting the reservoir into the fuel tank through the opening, and moving the fuel filter assembly with respect to the reservoir to a second position, thereby allowing the reservoir to be fully inserted into the fuel tank. In one aspect of the invention, moving the fuel filter assembly to the second position includes pivoting the fuel filter assembly with respect to the reservoir. In another aspect of the invention, moving the fuel filter assembly to the second position includes moving the fuel filter assembly linearly with respect to the reservoir.

The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of including and comprising and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items.
- FIGS.1-6 illustrate a
fuel pump module 10 embodying the invention. Thefuel pump module 10 can be inserted into afuel tank 14 havingtop wall 18, abottom wall 22, and four side walls 26 (only two are shown). Thetop wall 18 includes anopening 30 through which thefuel pump module 10 is inserted into thetank 14. The opening 30 is preferably circular, but can also be various other shapes. Thetank 14 is generally described as a low-profile tank, meaning that the distance between thetop wall 18 and thebottom wall 22 is substantially smaller than the distance between the top and bottom walls of standard prior art fuel tanks (not shown). - All of the components of the
fuel pump module 10 described below can be made of any suitable fuel resistant materials, such as fuel resistant conductive plastics. The use of conductive plastics also helps reduce and/or eliminate electrostatic charges that tend to build up in the fuel tank environment. - The
fuel pump module 10 includes areservoir 34 sized to fit through theopening 30. Thereservoir 34 is substantially cylindrical and has anouter wall 38 that defines aninterior portion 42 for housing fuel and other fuel pump module components as is commonly understood. Theouter wall 38 has respective upper andlower ends reservoir 34 is open on theupper end 46 and includes a reservoir inlet (not shown) on thebottom end 50. Thereservoir 34 can be made by injection molding or any other suitable plastic forming technique. - Further included in the
fuel pump module 10 is afuel pump 58 that communicates with the reservoir inlet and theinterior portion 42 to pump fuel. Thefuel pump 58 includes afuel inlet 62 that selectively receives fuel from either thetank 14 or theinterior portion 42, and afuel outlet 66 where fuel exits thefuel pump 58. Asuction filter 68 filters fuel just before it enters thefuel pump 58. Thesuction filter 68 is shown schematically and can be of any known configuration, including an elongated, member extending radially from thereservoir 34. The location of thesuction filter 68 is not critical. As shown in the figures, thefuel pump 58 is preferably located within theinterior portion 42 of the reservoir, however, the fuel pump could also be located elsewhere. - The
fuel pump module 10 also includes a fuellevel sensor assembly 70 pivotally mounted to thereservoir 34. The fuellevel sensor assembly 70 includes a rheostat fuel level sensing device (not shown) housed within a portion of theouter wall 38. A L-shapedarm 74 is pivotally connected to the rheostat device at one end, and supports afloat 78 on the other end. Thefloat 78 floats on the fuel in thetank 14 to provide a measure of the amount of fuel present in thetank 14 as is commonly known. It should be noted, however, that the use of a fuel level sensing device or any particular type of fuel level sensing device is not critical to the present invention. - The
fuel pump module 10 further includes aflange 82 supported above theupper end 46 of thereservoir 34 bysupport members 86. Theflange 82 is the same shape, preferably circular, as theopening 30 in thetop wall 18 of thetank 14 so that theflange 82 closes and seals theopening 30 when thefuel pump module 10 is fully inserted. Theflange 82 includes anelectrical connector 90 for providing electrical power to thefuel pump 58 and the fuellevel sensor assembly 70. Theelectrical connector 90 also provides for communication between the engine control unit (not shown), thefuel pump 58, and the fuellevel sensor assembly 70. Theflange 82 further includes anoutlet port 94 that allows fuel to exit thefuel tank 14 and enter the external portion of the fuel system (not shown). Theflange 82 also includes aninlet port 98 that allows unused fuel to be returned to thefuel tank 14. - The
fuel pump module 10 also includes an in-linefuel filter assembly 102 movably coupled to thereservoir 34. The in-linefuel filter assembly 102 includes a substantiallycylindrical filter housing 106 that houses filter media (not shown). Afuel inlet 110 and afuel outlet 114 communicate with the filter media to provide access to and from thefilter housing 106. Anextension member 118 extends from thefilter housing 106 and includes a radiused ortapered end 122 adjacent thefilter housing 106, and apivot end 126 spaced from thefilter housing 106. Thepivot end 126 is pivotally connected to thereservoir 34 at apivot point 128 adjacent thelower end 50. Any suitable pivoting connection, including the single pivot pin connection shown in the figures, can be used. The components of the in-linefuel filter assembly 102 can be manufactured and assembled in any suitable fashion. For example, thehousing 106, theextension member 118, thefuel inlet 110, and thefuel outlet 114 can be a single injection molded part capable of receiving and housing the filter media. Alternatively, theextension member 118 can be mounted in any suitable manner to a pre-existing in-line fuel filter. - A
flexible inlet conduit 130 is connected between thefuel pump outlet 66 and thefuel inlet 110 to provide communication between thefuel pump 58 and the in-linefuel filter assembly 102. - A
flexible outlet conduit 134 is connected between thefuel outlet 114 and theflange outlet port 94 to provide communication between the in-linefuel filter assembly 102 and the external portion of the fuel system. Fuel exiting thefuel pump 58 enters the in-linefuel filter assembly 102 where it is filtered to remove any debris present. The fuel then exits the in-linefuel filter assembly 102 and passes through the remainder of the fuel system before being injected into the combustion chamber (not shown) by the fuel injectors (not shown). - In a preferred embodiment, the
outer wall 38 of thereservoir 34 includes at least oneconduit channel 138 that houses portions of theflexible conduits conduits conduit channel 138 with any suitable securing straps or fasteners (not shown). Retaining theconduits conduit channel 138 helps prevent binding and damage to theconduits fuel pump module 10 into thetank 14. It should be noted, however, that theconduit channel 138 is not a necessary feature of the present invention. Thefuel pump module 10 can be installed successfully even when there is noconduit channel 138. - Installation of the assembled
fuel pump module 10 into thefuel tank 14 occurs as follows. - First, the in-line
fuel filter assembly 102 is oriented in a first or installing position (see FIG. 1), wherein the in-linefuel filter assembly 102 is substantially below thelower end 50 of thereservoir 34. Theextension member 118 is substantially in line with the edge of thereservoir 34. The in-linefuel filter assembly 102 is then inserted into theopening 30 as shown in FIG. 2 until thelower end 50 of thereservoir 34 is adjacent thetop wall 18. Thefloat 78 and a portion of the L-shapedarm 74 also enter thetank 14 through theopening 30. - Next, the entire
fuel pump module 10 is moved laterally so that thereservoir 34 is aligned with the opening 30 (see FIG. 3). This lateral movement shifts the in-linefuel filter assembly 102 laterally inside thetank 14. Thereservoir 34 is then partially inserted into the tank (see FIG. 4) until the in-linefuel filter assembly 102 contacts thebottom wall 22. As insertion continues, the in-linefuel filter assembly 102 pivots (see FIG. 5) with respect to thereservoir 34 about thepivot point 128. Pivoting is aided by the radius on theradiused end 122 of theextension member 118, which encourages pivoting upon engagement with thebottom wall 22. - As the in-line
fuel filter assembly 102 pivots, thereservoir 34 is inserted into thetank 14 until thelower end 50 rests on the bottom wall 22 (see FIG. 6). When thereservoir 34 is resting on thebottom wall 22, theextension member 118 is substantially normal to the longitudinal axis of the reservoir 34 (which is substantially vertical in FIG. 6), and at least a portion of theextension member 118 rests on thebottom wall 22. The in-linefuel filter assembly 102 is now in its second or operating position. As seen in FIGS. 1-6, the in-linefuel filter assembly 102 is preferably pivoted approximately ninety degrees during the installation process to move from the installing position to the operating position. - When the
fuel pump module 10 is installed, thefloat 78 rests on thebottom wall 22. Additionally, theflange 82 closes and seals theopening 30.Appropriate connection lines 142 can be connected to theelectrical connector 90, theoutlet port 94, and theinlet port 98. - FIGS.7-13 illustrate a
fuel pump module 200 that is an alternative embodiment of the present invention. Many of the features of thefuel pump module 200 are substantially the same as thefuel pump module 10 and will not be described again. Like parts have been given like reference numerals. - The
fuel pump module 200 includes an in-linefuel filter assembly 302 having acylindrical housing 106, filter media (not shown), afuel inlet 110, and afuel outlet 114 substantially identical to the corresponding features described with respect to the in-linefuel filter assembly 102. The difference between the in-linefuel filter assembly 302 and the in-linefuel filter assembly 102 is the manner in which the in-linefuel filter assembly 302 moves with respect to a slightly modifiedreservoir 234. The in-linefuel filter assembly 302 includes anextension member 318 connected to thecylindrical housing 106. Theextension member 318 has alower end 322 adjacent thecylindrical housing 106 and anupper end 326 spaced from thecylindrical housing 106. Theextension member 318 is preferably T-shaped in cross-section (see FIG. 13), but could also have other cross-sectional configurations (e.g., L-shaped, triangularly shaped, and the like). - The
reservoir 234 has anouter wall 238 with agroove 242 for slidably receiving theextension member 318. To accommodate the T-shaped cross-section of theextension member 318, thegroove 242 includes (see FIGS. 8-10 and 13) alateral slot 246 that extends the length of thegroove 242. When positioned in thegroove 242, theextension member 318 is constrained to linear movement within the groove along the length of the groove 242 (upward or downward in FIGS. 7-12). If the extension member has other cross-sectional configurations, thegroove 242 can have a corresponding configuration to enable the same linear movement of theextension member 318. Thegroove 242 can be formed in any suitable manner, including being integrally formed during the molding of thereservoir 234 or being machined into a previously formedreservoir 234. - Unlike the pivoting relationship between the
reservoir 34 and the in-linefuel filter assembly 102, the in-linefuel filter assembly 302 is linearly movable with respect to thereservoir 234, preferably in a slidable manner. In addition to sliding with respect to thereservoir 234, the in-linefuel filter assembly 302 could alternatively be telescopically coupled to thereservoir 234 such that a telescoping extension member (not shown) would achieve the same end result as the slidingextension member 318. The telescoping extension member could include several nestable segments that would telescopically extend and collapse as needed to allow installation of thefuel pump module 200. - Installation of the assembled
fuel pump module 200 into thefuel tank 14 occurs as follows. First, the in-linefuel filter assembly 302 is oriented in a first or installing position (see FIG. 7), wherein the in-linefuel filter assembly 302 is substantially below thelower end 50 of thereservoir 234. Theextension member 318 is received in thegroove 242 such that theupper end 326 is adjacent thelower end 50 of thereservoir 234. Any suitable method of retaining theextension member 318 in the slot can be used, including a tight fit between theupper end 326 and the lower portion of thegroove 242, various stop configurations in thegroove 242 and/or on theextension member 318, or even by limiting the length of theconduits fuel filter assembly 302 is then inserted into theopening 30 as shown in FIG. 8 until thelower end 50 of thereservoir 234 is adjacent thetop wall 18. Thefloat 78 and a portion of the L-shapedarm 74 also enter thetank 14 through theopening 30. - Next, the entire
fuel pump module 200 is moved laterally so that thereservoir 234 is aligned with the opening 30 (see FIG. 9). This lateral movement shifts the in-linefuel filter assembly 302 laterally inside thetank 14. Thereservoir 234 is then partially inserted into the tank (see FIG. 10) until the in-linefuel filter assembly 302 contacts thebottom wall 22. As insertion continues, thereservoir 234 slides down the extension member 318 (see FIG. 11) so that theupper end 326 approaches theupper end 46 of thereservoir 234. - The
reservoir 234 is inserted into thetank 14 until thelower end 50 rests on the bottom wall 22 (see FIG. 12). When thereservoir 234 is resting on thebottom wall 22, the in-line fuel filter assembly is adjacent thereservoir 234 such that the lower end 322 (not shown in FIG. 12) of theextension member 318 is adjacent thelower end 50 of thereservoir 234 and theupper end 326 is adjacent to or upwardly spaced from theupper end 46 of thereservoir 234. The in-linefuel filter assembly 302 is now in its second or operating position. As seen in FIGS. 7-12, theextension member 318, and thus the in-linefuel filter assembly 302 slides linearly with respect to thereservoir 234 during the installation process to move from the installing position to the operating position. - Again, when the
fuel pump module 200 is installed, thefloat 78 rests on thebottom wall 22. Additionally, theflange 82 closes and seals theopening 30.Appropriate connection lines 142 can be connected to theelectrical connector 90, theoutlet port 94, and theinlet port 98. - The
fuel pump modules fuel pump modules - For example, it is possible to use the present invention with a reservoir that already includes a smaller in-line filter. By adding one of the in-
line filter assemblies - It should also be recognized that the
fuel pump modules fuel pump modules fuel pump modules fuel pump modules fuel filter assemblies - Various features of the invention are set forth in the following claims.
