Claim 13:
14. A filter assembly comprising:
a filter head comprising:
a filter head coupling surface defining a filter head opening;
a filter head outlet configured to provide a fluid;
a filter head inner wall extending around the filter head outlet; and
a filter head outer wall extending around the filter head inner wall, the filter head inner wall and the filter head outer wall collectively defining a filter head channel; and

a filter cartridge comprising:
a filter cartridge shell having a filter cartridge coupling surface configured to be coupled to the filter head coupling surface, the filter cartridge shell defining a filter cartridge opening; and
a filter element configured to be contained within the filter head opening and the filter cartridge opening when the filter cartridge coupling surface is coupled to the filter head coupling surface, the filter element comprising:
filter media coupled to a first endcap;
the first endcap comprising:
a first endcap flange interfacing with the filter media;
a first endcap inner wall contiguous with the first endcap flange, the first endcap inner wall projecting orthogonally from the first endcap flange;
a first endcap outer wall contiguous with the first endcap flange, the first endcap outer wall projecting orthogonally from the first endcap flange and interfacing with the filter media, the filter media extending between the first endcap inner wall and the first endcap outer wall; and
a first lip section contiguous with the first endcap outer wall and extending from the first endcap outer wall away from the first endcap inner wall; and

a seal member coupled to the first endcap and configured to be received within the filter head channel when the filter element is contained within the filter head opening and the filter cartridge opening,

wherein the filter cartridge shell comprises an edge that supports the first lip section within the filter head opening when the filter element is contained within the filter head opening and the filter cartridge opening.
