Abstract: A filter assembly includes a filter housing, a filter housing lid, a filter cartridge, an endplate, and a seal member. The filter housing defines a first cavity and comprises a return passage in fluid communication with the first cavity. The filter housing lid is selectively coupled to the filter housing and defines a second cavity coextensive with the first cavity. The filter cartridge is positioned within the first cavity. The endplate is coupled to a first end of the filter cartridge. The endplate is configured to interface with the filter housing. The seal member is coupled to the endplate and is configured to be received in the return passage. The endplate is configured to partially separate the filter housing from the filter cartridge.
