ABSTRACT:
A fuel filter assembly employs a retainer collar for locking the disposable cartridge to the base. The base and the retainer collar are configured with a pair complementary spiral ramp-like structures. The retainer collar is rotatable so that the catches are positioned in slots of the base for locking the cartridge to the base. A spring washer biases the retainer collar into the locked position.
