ABSTRACT:
A fuel filter assembly employs a base which mounts a disposable filter element cartridge and includes a sump for collecting water removed from the filtering unit. The cartridge includes a dual stage filter system wherein fuel flows axially to an upper 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 fule flows axially downwardly and through an outlet passage from the base. The water collected in the sump is removed through a drain cock.
