Abstract
A spin-on water-separating fuel filter has a built-in central drain tube for providing a sump port at the connection end of the spin-on filter located near the fuel inlet and fuel outlet ports. Water removed from the fuel is collected in a sump at the base of the filter. The drain tube, supported in the bore of the filter element, has a sump end projecting into the sump, and an outlet end adjacent to and aligned with a central threaded opening at the connection end of the filter. The outlet end of the drain tube, self-centered near the threaded opening, has a captured gasket which forms the sump port. When the filter is installed on the mounting head, the outlet end of the drain tube is coupled to a short stub tube projecting from the center of the central threaded neck to form a sealed passage for evacuating water from the sump.
