ABSTRACT:
A fuel filter assembly (10) includes a housing (12) with an internal chamber (14) and inlet and outlet (18, 22). The chamber is bounded by an annular wall (16) and has an opening (30) at an upper end thereof. An element (26) is accepted in the chamber. The element includes a manually engagable cap portion (28) for closing the opening, and a disk-shaped member (46). The disk-shaped member has a deformable lip portion (50) for engaging the annular wall, and for fluidly separating an aperture (24) in connection with the outlet fitting, from aperture (24) in connection with the outlet fitting, from an aperture (20) in fluid communication with the inlet fitting. A check valve (200) is also engaged by the lip portion to open a fluid path to the chamber when the filter element is located in the housing. A media body (54) of filter media (56) removes impurities from liquid flowing therethrough. Fuel flows from the inlet to the chamber and then through the media. From an interior area (60) of the media body, the fuel passes through a passage (62) into an intermediate area (52) and out the outlet. An element change may be accomplished without spilling or contacting the fuel, and without contaminants in the chamber reaching the aperture in fluid communication with outlet.
