Function

The fuel pump draws the fuel from the swirl pot and drives it to the fuel filter with the integral fuel pressure regulator. While cornering when the fuel level is low, the swirl pot prevents the fuel pump from drawing air.

The fuel pump is actuated via the fuel pump relay or the fuel pump control unit (engine 272.985).

The voltage supply is fuse protected.
