Abstract
Fuel pump assemblyincludes a filterthat rests on ledge, between the pump housingand inlet cap. Filter detectorhas a valve engagerfor opening the check valveand bearing feetthat engage the perimeter of the filter. When the filter is absent from the pump, the bearing feetof the filter detector move beyond the ledgeinto the recessand the valve engager stemretracts from the check valveand the valve closes to terminate flow of fuel to the pump. The inlet and outlet capsandare rotatably mounted to the intermediate body of the pump to allow the fuel inlet and outlet to be oriented at angular intervals about the pump. A progressive seal is formed at the O-ringbetween the inlet end capand the fuel pump housing to continue the seal as the end cap is removed or reassembled with the housing so that the check valve is closed before the housing is opened.
