75 Fuel tank

M3/5 Fuel pump with fuel tank sensor

Location

The fuel pump with the fuel level sensor is integrated in the fuel tank.

Task

The fuel pump with fuel level sensor provides a sufficient quantity of fuel to the high-pressure pump and at the required pressure.

Design

2-stage flow pump integrated in fuel feed module.

Function

The fuel pump with fuel level sensor is actuated by the CDI control unit via the fuel pump relay (K40/9k3) (N3/21).

It draws the fuel from the fuel feed module through a fuel strainer. The fuel pump then pumps the suctioned fuel via the fuel filter on to the high-pressure pump (M41).
