A fuel filter assembly of modular form is adapted to incorporate a lift pump or an automatic primer. The lift pump is mounted to the filter base by means of a lock ring. Fuel supplied to the filter base inlet is supplied to a rotary vane-type or gerotor pump which may be electrically activated from the vehicle console or a location remote from the fuel filter assembly. The lift pump regulates the fuel pressure to provide a sufficient fuel flow through the supply system and the filter for ultimate delivery to the fuel injection pump or engine. The pump/filter flow sequence is bi-directional and may be selected by the angular position of an adapter.
