The bracket is made in the form of an elongated, curved plate, one edge of which is bent along the length, longitudinal grooves are extruded along the axis axis, and in the middle part there are holes for fixing the fuel level sensor, and the bracket is made of metal. The outlet and inlet pipelines are made of plastic, for example, polyamide. The device contains two nozzles passing through the cover and rigidly and hermetically connected to it, the end of one nozzle extending into the inside of the cover is connected by a pipeline to the gasoline pump, its other end is designed to connect to the ICE supply line, the inner end of the second pipe is connected to the fuel drain pipe, and its other end is with a fuel drain line, and the nozzles and cover are made of metal. Pipelines and electrical wires are fixed to the bracket with ties. The bracket, cover and nozzles are made as a whole and made of plastic.

This module also has a rather complicated design and high metal consumption and, as a consequence, the high cost of the module.

The closest in technical essence and the achieved result is the gasoline pump module according to patent No. 78529, IPC F02M 37/10, publ. 11/27/2008, which includes a chamber, an jet jet pump, a fuel level sensor, a fuel pressure regulator, a cover, while the receiving funnel of the jet pump is made in the module chamber, and the nozzle located in its housing has a direct channel, while the housing is connected on the latches to the chamber, the fuel pressure regulator is fixed in the lid with a plastic clip with an antennae of the corresponding shape, which ensures installation between the fuel pressure regulator and the lid during installation, and when disassembling - divergence and emphasis in it, for installation the clips in the cover are grooves, the fuel level sensor is secured by two cylindrical guides passing through the holes on the fuel level sensor, the fuel pressure regulator is earthed by a metal part mounted on the cylindrical part of the regulator and fitted by springing properties, the protruding part of the ground serves to connect any electrical connector.

Common signs with the claimed utility model is the presence of a cover, a chamber, a fuel level sensor, a fuel pressure regulator, a strainer, an electric gas pump.

Signs that impede the achievement of the technical result are the lack of a fine fuel filter, the fitting for connecting the fuel supply pipe of the engine together with the cover and the vertical location of the "Christmas tree" for mounting the tube, the fuel level sensor in the vertical position on the side of the chamber.

The objective of the utility model is to improve the operational characteristics of the device.

The technical result consists in expanding the functionality due to the fine cleaning of the fuel and increasing the useful space inside for expanding or adding module units within the given dimensions.

The technical result is achieved by the fact that the gasoline pump module includes a cover, a chamber, a fuel level sensor, a fuel pressure regulator, a strainer, an electric gasoline pump, while the module contains a fine fuel filter mounted on the camera, a fitting for connecting the engine fuel supply pipe is made separately from the cover and connected through the o-ring on the latch with the cover in a horizontal position, on the portion of the fitting located inside the cover there is a “herringbone” for pressing the tube in, deck contacts and to connect the vehicle wiring harness having a flat shape and arranged vertically, the fuel pressure regulator is provided with fixing screw; grounding of the pressure regulator is performed by clamping a wire or ring connected to the wire by a screw securing the regulator; metal axes (guides) are pressed into the cover, the fuel level sensor is located at an angle relative to the vertical, the anti-drain valve made in the form of a fungus is riveted directly to the camera, the float has a rounded shape, a protrusion in the shape of a rectangle or expanding on the cover for positioning relative to the tank during installation protrusion with a groove.

In more detail, the claimed device is discussed in the drawings.

The petrol pump module consists of:

1 - cover; 2 - axis guide; 3 - fuel filter; 4 - camera; 5 - fuel level sensor; 6 - a float; 7 - fitting for connecting the fuel supply pipe of the engine; 8 - contacts connecting car harness; 9 - anti-drain valve; 10 - fuel pressure regulator; 11 - screw fastening the regulator; 12 - a sealing ring; 13 - Christmas tree press-fit tube; 14 - latch securing the fitting; 15 - wire and ring for grounding the fuel pressure regulator; 16 - protrusion for positioning the module relative to the tank during installation.

The fuel pump module has a fuel fine filter 3, designed for the entire life of the module; the nozzle 7 for connecting the fuel supply pipe of the engine is made separately from the cover and is connected through the o-ring on the latch to the cover 1 in a horizontal position, there is a “herringbone” on the section of the fitting located inside the cover for pressing the tube in, the horizontal location of the nozzle allows you to reduce the height of the module or use the free space to expand the dimensions of the devices inside the module or add new ones, the removable design of the nozzle allows the use of various nozzles for various Diameter of fuel lines; the contacts of the pads 8 for connecting the vehicle harness are flat and vertically arranged, which increases the manufacturability of the module cover; the fixation of the fuel pressure regulator 10 is carried out by a screw 11; grounding of the pressure regulator is carried out by clamping the wire 15 or the ring connected to the wire by the screw of the regulator; metal axes (guides) 2 are pressed into the cover, the fuel level sensor 5 is located at an angle relative to the vertical, which allows you to remove the mounting parts of the fuel level sensor from the outside of the module body parts and thereby increase the usable space for other module elements; a fungus-shaped anti-drain valve 9 is attached directly to the chamber 4, which eliminates additional details to ensure its operation; the float 6 has a rounded shape, which prevents the float from taking a vertical position when the fuel level is less than half the width of the float; on the lid for positioning relative to the tank during installation there is a protrusion 16, which may be in the form of a rectangle or an expanding protrusion with a groove.

The gasoline pump located in the intake module chamber draws fuel from the tank and feeds it into the integrated fine filter. After the filter, the fuel is distributed: part (excess) goes to the fuel pressure regulator, where it merges to provide the specified pressure, the other part enters the car engine. Excess fuel passing through the regulator enters the jet pump housing and then into the nozzle. As a result, due to the ejection effect, additional fuel is pumped into the intake chamber from the tank and the fuel level in the chamber becomes higher than the level in the tank. The module’s chamber is used to mount the fuel level sensor (FLS).

The proposed design allows you to expand the functionality of the device and increase the usable space inside to expand or add module nodes within the specified dimensions.
