A fluid filter has an outer case with a side wall, a closed first end wall, and a second end wall defining fluid inlet and outlet openings, as well as a filter cartridge received within the outer case. The filter cartridge includes a substantially cylindrical full flow filter element, providing for passage of a major portion of fluid entering the filter, and a substantially cylindrical bypass filter element, providing for passage of a minor portion of fluid entering the filter and disposed radially within and surrounded circumferentially by the full flow filter element. By way of the particular fluid filter configuration disclosed, a simple alternative to known filters having full flow and bypass filters located in common housings is provided.

Full flow liquid filter with integral bypass filtration

An improved filter for liquid fuel housing an elongated tubular housing with a cylindrical wall and having an inlet end and an outlet end and including an integral inlet connector portion at the inlet end and an integral outlet connector portion at the outlet end and a filter element positioned within the tubular housing and having filter media defining a central passageway closed at one end, the passageway having an opposite end in communication with the housing outlet connector portion, the filter media having an external surface in communication with the housing inlet connector portion so that liquid fuel flowing through the housing flows through the filter media, the housing cylindrical wall being formed of an inner wall portion and an outer wall portion with a space therebetween providing a housing that resists static electric induced sparks passing therethrough.
