1. A filter assembly comprising:
a filter housing defining a first cavity and comprising:
a first surface, and
a return passage in fluid communication with the first cavity, the return passage extending through the first surface;
a filter cartridge positioned within the first cavity, the filter cartridge centered on a center axis;
an endplate coupled to a first end of the filter cartridge, the endplate configured to partially separate the filter housing from the filter cartridge, the endplate comprising an endplate aperture extending around the center axis; and
a seal member extending around the center axis, the seal member comprising:
a seal member projection configured to be received within the endplate aperture so as to couple the seal member to the endplate; and
a seal member flange integrally formed with the seal member projection and configured to be received in the return passage when the endplate is in confronting relation with the first surface, protrude from the endplate when the seal member projection is received within the endplate aperture, and deflect relative to the seal member projection when the seal member projection is received within the endplate aperture.
