Abstract: A filter element (16) may include a tubular element (26) defining an internal space (32), and a retainer element (34) associated with a first end (28) of the tubular element (26), wherein the retainer element (34) is configured to be coupled to a first housing (14). The filter element (16) may also include a valve seat member (36) in the internal space (32). The valve seat member (36) may include a valve seat aperture (38) configured to provide a fluid seal with a valve poppet (40). The filter element (16) may further include first and second end caps (42, 46) associated with ends (28, 30) of the tubular element (26). The filter element (16) may also include filter media (50) around the tubular element (26), and the second end cap (46) may be configured to provide a fluid seal (76) between the filter element (16) and a drain passage (24) in a second housing (18), such that as the filter element (16) is separated from the second housing (18), fluid flows from the filter element (16) into the drain passage (24).
