ABSTRACT:
A fuel filter assembly employs a base which mounts a disposable filter element cartridge. The cartridge 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. Water may be collected in a sump. The cartridge is retained on the base by a collar which engages against a roll seam structure of the cartridge.
