A filter assembly (18) includes a replaceable filter element (56) disposed within a filter housing (50). The housing (50) includes a removable cover (51), and a fitting (60) including an internal central conduit (72) extending along the central axis of the housing (50). The central conduit (72) is bisected along its length by a wall (74) into a pair of flow channels (76, 78) connected to a pair of ports (28, 16) in the fitting (60). Another port (22) is provided in the fitting (60) and a still further port (26) is provided in the housing (50). The filter element (56) includes a first circular imperforate end cap (110), and a second annular imperforate end cap (112) dimensioned to receive the central conduit (72). First and second filter media loops (124, 125) are supported between the first and second end caps (110, 112). An imperforate cylindrical wall (156) is radially disposed between the first and second filter media loops (124, 125). Annular seals (123, 150, 158) are provided around the opening in the second end cap, at the inner end of the first filter media loop, and at the inner end of the cylindrical wall. The seals (123, 150, 158) provide a fluid seal against the central conduit (72) when the filter element is installed in the housing to fluidly separate two flow paths through the housing (50).
