FILTER CARTRIDGE ASSEMBLY AND METHOD OF MANUFACTURE THEREOF

摘要

A filter cartridge has a longitudinal axis. A cartridge housing has first and second shell portions. The first shell portion has a cartridge housing opening and an annular element retention lip which is disposed axially inward of the opening and coaxial with the longitudinal axis. The filter element has a first end cap, a second end cap, and a continuous ring of filter media disposed between the first and second end caps. The first end cap defines a fuel flow port which is coaxial with the longitudinal axis. A plurality of resilient element retention arms extend axially from the first end cap, and surround the fuel flow port. The arms terminate in retention barbs which are mateable with the annular lip. The resilient retention arms hold the retention barbs against the annular lip, suspending the filter element within the cartridge.
