Abstract
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.
