More Information
Summary:A fuel filter assembly employs a base which mounts a disposable filter cartridge. A pair of axial conduits in the base provide fluid communication between the base and the cartridge. An axial sealing member mounted in the cartridge receives the axial conduits. An axial conduit and preferably at least one baffle positioned on the axial conduit outer surface within the cartridge provide a flow path through the cartridge. An orifice located in the cartridge axial conduit provides a bleed vent which controls the size and flow rate of air bubbles in filtered fuel exiting the fuel filter. A flange-shaped end of the cartridge axial conduit engages a ridge on the outside surface of the sealing member to prevent the fuel flow from bypassing the baffle.
