The filter has a filter media that allows fluid to be filtered therethrough, and has an endplate with an opening that allows fluid to flow into or out of the filter media. The endplate has a main surface with an elliptical spud protruding outward from the main surface and surrounding the opening. An oval seal is disposed about an outer surface of the elliptical spud. The housing is releasably connected to the filter, and has a mounting component. The mounting component has an elliptical boss that mates with the elliptical spud and seals against the oval seal.
