Definitions
- fuel injection systems such as, for example, pump-nozzle systems (UI) or high-pressure accumulator injection systems (common rail)
- UI pump-nozzle systems
- common rail high-pressure accumulator injection systems
- plastic pipes used in addition to a high-pressure pump, a high-pressure reservoir body, pump-nozzle units and the fuel injectors in the return region for the fuel, i. on the low-pressure side of the injection system, plastic pipes used.
- plastic molding tubes of the fuel such as taxed control amount or amount of leakage, which occurs during actuation of the fuel injectors, returned within the fuel system back into the tank.
- the tubes used within the low pressure range are generally preformed tubes made of plastic, which often have a deviating from the straight line shape due to the installation conditions and arcuately curved.
- Plastic molding tubes may have a deviating from the line shape with respect to the inner contour and an independent, geometrically different outer contour.
- Plastic tubes that carry fuel must meet high strength requirements and also have a high security against bursting in the event of an accident.
- the plastic molding tubes used in the fuel system in the low-pressure side return region can be manufactured with or without throttle, which depends on the pressure to be maintained in the low-pressure region.
- Plastic molding tubes, which have a bow or a bent portion or the like can not be formed with respect to the inner contour or only relatively complex.

- the first plug part 26 of the combined plug module 24- which is possible only after the return component 38 has been dismantled-can be removed from the plug bore 31 of the add-on component 10. Accordingly, it is protected from entering fuel as long as the first plug part 26 with the plug seal 28 accommodated in it remains in the plug bore 31.
- the forced sequence proposed according to the invention during disassembly of the combined plug module 24 from the add-on component 10 ensures that the fuel in the low-pressure or return region does not penetrate into the plug bore 31 after removal of the return element 38 in the removal direction 86 and into the plug contact region flows, since the first connector part 26 with it received plug seal 28 prevents this.

- a pin 160 is retracted so far that an O-ring 146 from the return bore 112 is disengaged and the fuel, which is in the return, can flow out.
- this does not get into the plug hole 131, since this is due to the forced expiration, is closed.
- the complete disassembly of the plug module 124 may optionally be in two parts, as in the basic version, or in one piece.
- the securing tab 162 is actuated in the withdrawal direction 195, so that the securing tab extensions 157, 159 are disengaged from the axial rest stops 100, 101.
- the return component 138 can be deducted from the first connector part 126. The further dismantling takes place as described in connection with the basic version.
