Fuel filter.

摘要

A fuel filter assembly employs a base (12) which mounts a disposable filter element cartridge (14). The cartridge (14) includes a dual stage filter system wherein fuel flows axially to a primary filter element for removing particulate matter and coalescing water droplets and axially to a secondary filter stage which functions as a water barrier. The filtered fuel flows axially and exits through an outlet passage in the base (12). Water may be collected in a sump. The cartridge (14) is retained on the base (12) by a collar (62) which engages against a roll seam structure of the cartridge (14).
