ABSTRACT:
A key system for a fuel filter assembly employs angularly spaced arcuate protrusions which protrude radially from the cylindrical sidewall of the cartridge. The base has corresponding tracks defined by equidistantly spaced rails which engage with the protrusions to key the cartridge with the base. The key system is employed either apart from or in conjunction with a second axial key/slot system of the base and the cartridge.
