A fluid filter assembly of a filtration system is described. The filter assembly described includes a cover member and a filter cartridge having at least one filter element and a plate member. The plate member includes a seal surface on one side facing the cover member, and a seal surface on another side facing away from the cover member. The seal surface facing the cover member is configured to seal with the cover member, and the seal surface facing away from the cover member configured to seal with another component of the filtration system. The assembly provides a structure that can retain a seal between sealing surfaces of the cover and the filter cartridge, at least while the fluid filter assembly is being serviced, so as to at least minimize fluid dripping and leakage.

A fuel-water separation filtration system for filtering fuel and for separating water out of the fuel includes a housing assembly, a filter element assembly, and a closing lid. The housing assembly includes a unitary molded housing, a plurality of flow connection fittings that are spin welded into the housing, and a standpipe that is spin welded to the housing. The filter element assembly includes a cover and an endplate and filter media with one end bonded to the cover and an opposite end bonded to the endplate. The standpipe includes an attachment portion that extends beyond the upper end of the filter element assembly and the closing lid is threadedly attached to the attachment portion for closing the housing assembly. The filtration system requires pressurization for proper operation and the filtration system cannot be pressurized without the filter element assembly being installed.
