<p>A fuel filter (20) constructed with a heater (30) and designed for fuel-water separation includes a unitary housing (21) which is closed by a threaded lid (22). A surrounding sidewall defines an interior space (68) with a water collection area (65). A filter cartridge including a filter element (72), centertube (71), and top and bottom endplates (75, 78) is disposed in the interior space (68). The lid (22) includes snap-fit fingers (76) arranged for press-on attachment to the top endplate (75). A heater ring (30) is provided and is positioned around the filter cartridge (64). The heater ring (30) provides a flow path for entering fuel and positive-temperature-coefficient stones (138) which assist in heating the fuel. Control of the heater ring (30) is provided by a heater connector and thermostat combination (26). A drain valve (24) is mounted to the housing (21) in flow communication with the water collection area (65). A water-in-fuel sensor (25) is mounted to the housing and extends into the water collection area (65).</p> |
