ABSTRACT:
A fluid filter assembly which is constructed and arranged to threadedly mount onto an engine block mounting base includes an enclosing outer shell, a filtering element positioned within the outer shell so as to define an annular clearance space between the outer shell and the filtering element. A nutplate is assembled to the outer shell so as to close the outer shell and provide an internally-threaded mounting portion for attachment to the engine block mounting base. The sidewall which defines the threaded mounting portion is free of any flow openings therethrough. A seal arrangement including an inner seal positioned between the nutplate and the filter element and an outer seal positioned between the engine block mounting base and the nutplate is provided as part of the fluid filter assembly. The nutplate and inner seal are designed to cooperate with each other so as to define a plurality of flow passageways extending between the nutplate and inner seal and providing a flow path from the engine block mounting base to the annular clearance space.
