A valve stem (48) is sized to mate with a filter housing (30) bore. The valve stem (48) has a first and second end (60) and a body (62). The first end (58) includes a threaded stem portion (64) configured to mate with a corresponding threaded filter portion. The second end (60) has a drain outlet (82) and includes a fitting (84) for a tube (86). The body (62) has an axial passage (90) disposed therethrough. The axial passage (90) has a divider (92) disposed axially along at least a portion thereof. The divider (92) separates the axial passage (90) into an outlet passage (94) (94) and a vent passage (96). The outlet passage (94) (94) is open at the first end (58), at the drain outlet (82) and at a first side passage (104). The vent passage (96) is closed at the first end (58), open at a second side passage (106), open at the drain outlet (82), and open at a vent side passage (100).
