Fuel Filter Assembly and Cartridge

A filter assembly comprising:

• a head having a cartridge receptacle and defining a first axial passage and a second axial passage extending to said cartridge receptacle, said head mounting a shaft and a retainer engaged with said shaft and extending into said receptacle, said retainer including an arm terminating in a latch;
• a filter cartridge received in said cartridge receptacle and comprising:
• a housing, a filter element positioned within said housing having filter media arranged to separate an interior volume of said cartridge into unfiltered and filtered regions so that fluid passing through said filter media moves from said unfiltered to said filtered region, and
• a communication hub substantially spanning a first end of said housing and engaged thereto, said hub having a first axial conduit in communication with said unfiltered region and having a circumferential sealing surface sealing with said first axial passage, a second axial conduit in communication with said filtered region and having a circumferential sealing surface sealing with said second axial passage, said hub defining a well;
• a keeper module disposed above said hub and forming a retainer receiving aperture providing access to said well and a keeper adjacent said aperture;
• wherein said retainer extends through said aperture into said well, said latch engages said keeper wherein rotation of said shaft in a first direction draws the retainer toward the head to exert an axial retention force to secure said cartridge in said cartridge receptacle with said first axial passage in fluid tight communication with said first conduit and said second axial passage in fluid tight communication with said second conduit, and wherein rotation of said shaft in a second direction releases the latch away from the keeper.
