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.

[ What is claimed is:] [1.] A filter comprising:a housing including a filter chamber, the housing including an opening to said filter chamber, said filter chamber bounded by a generally longitudinally-extending, imperforate annular wall adjacent said opening;first fluid port and a second fluid port into said filter chamber;one of said fluid ports including a valve member normally spring-biased into a closed position to block fluid flow through said one port;a removable filter element in said filter chamber, said filter element having a ring of filter media, said ring defming an interior area and an exterior area in said filter chamber;said filter element further including a disk-shaped member attached to a first end of said filter media ring, said disk-shaped member having unitary therewith an annular lip portion extending axially from said disk-shaped member toward a second end of said filter element and circumferentially surrounding an axial extent of the filter media ring, said lip portion also projecting radially outward from the media ring and sealingly engaged circumferentially around said annular wall to fluidly separate said interior area from said exterior area of said filter chamber such that said first port is fluidly connected to said interior area and said second port is fluidly connected to said exterior area, said lip portion also engaging said valve member and positioning said valve member in an open position to allow fluid flow through said one port.
