Abstract
A fuel filter cartridge is formed from a pair of shell sections which are joined along a roll seam to form a retaining shoulder. The sections have generally cylindrical walls which are symmetric about a central axis. One of the sections has a diameter greater than the other section. Angularly spaced arcuate protrusions or keys protrude radially from the cylindrical wall of the cartridge.
