The pump module takes fuel from both sides of the fuel tank and supplies it to the fuel delivery line via the PVV and the mounting flange. The pump module is mounted in the RH (right-hand) side of the fuel tank, on a bayonet fitting welded to the bottom of the fuel tank.
A swirl pot is integrated into the base of the pump module housing. A 60 micron filter is attached to the swirl pot inlet at the base of the housing.
The fuel pump is an electric, variable speed, vane pump installed in the top of the housing. The pump has a maximum rated flow of 234 liters/hour (61.82 US gallons/hour) at 12.2 V and 4.5 bar (65.3 lbf/in.2 ).
The inlet of the fuel pump is located in the center of the swirl pot. Pipes connect the two outlet ports of the fuel pump to the PVV and to a jet pump on top of the housing. The jet pump draws fuel from the LH (left-hand) side of the fuel tank through a suction pipe connected to the remote pump housing. A 'spider trap' in the remote pump housing prevents the ingress of larger pieces of debris.
Operation of the fuel pump is controlled by the FPDM. The fuel pump is connected to the FPDM via an electrical connector on the underside of the mounting flange.
