Abstract
A fuel filter constructed and arranged for fuel-water separation which is designed with an integral fuel pump includes a unitary housing designed with a fuel filter cavity for receipt of a fuel filter cartridge, and a pump receptacle cavity for receipt of a fuel pump. A separating wall is disposed between the fuel filter cavity and the fuel pump cavity and this wall defines a flow passageway for fuel flow communication between the fuel pump and the fuel filter. Included as part of the fuel filter assembly is a lid designed to attach over the fuel filter cavity of the unitary housing and a lid designed to attach over the pump receptacle cavity of the unitary housing. The combining of the fuel filter cartridge and the cooperating fuel pump within the same unitary casting provides design efficiencies and economies.
