AWD

Operation






Operation of the all wheel drive (AWD) main fuel pump module is similar to the FWD with the addition of a auxiliary fuel pump module with a auxiliary fuel level sending unit and draws fuel from the base of the auxiliary fuel pump module (2) through an internal tube.

The auxiliary fuel pump module flow rate is greater than the vehicle fuel consumption rate so that the auxiliary side of the tank is emptied before fuel is depleted from the primary side.
