Abstract
A filter element has a first end cap and a ring of filter media. The first end cap includes structures projecting from the periphery to form a keyed connection with a filter bowl and filter head. Some of the projections are fixed lugs, while other projections are latch fingers arranged to move in an axial direction during mounting and dismounting of the filter assembly components. The filter element first end cap is configured to mate with the upper end of a filter bowl to form an element/bowl assembly. The mated structures of the element and bowl form the male part of a bayonet connection. The filter head defines a corresponding female bayonet connector part. The latch fingers retain the element to the bowl and the assembled element and bowl to the filter head.
