75 Fuel tank
Location
The fuel tank is located at the front in the luggage compartment.
Design
The fuel tank is made of steel plate.
There are several baffle plates inside the tank to prevent splashing noises.
When the fuel tank is full, a float valve closes off the fuel filler neck. This ensures that the refueling nozzle shuts off more rapidly and overfilling is largely prevented.
there is a fuel level sensor at the side of the fuel feed module for detecting the fuel level (B4).
The fuel pump (M3) is built into the fuel feed module. A fuel strainer (fuel prefilter) is installed under the fuel pump in the feed line.
At the bottom of the fuel pump module there is a suction jet pump, which fills the fuel feed module when the fuel level is low.
The housing of the fuel delivery module serves as a swirl pot. While cornering when the fuel level is low, the swirl pot prevents the fuel pump from drawing in air.
The fuel tank has no drain valves. It is drained using an appropriate extractor system, or through the tank draining service using the fuel pump control unit (N118).
Function
The fuel pump draws fuel from the bottom of the fuel feed module through the fuel strainer, and pumps it through the fuel filter with fuel pressure regulator to the fuel distribution rail (one-line system). The fuel pressure is limited to about 5.0 bar by the fuel pressure regulator.
The fuel return from the fuel pressure regulator flows back into the fuel feed module and drives a suction jet pump.
