ABSTRACT:
A fuel filter and method of making same provides an in-tank filter having a novel fitting and seal construction. The filter includes a fabric body and a spacing structure disposed within the body to prevent collapse of the filter and accompanying reduction of or interference with fuel flow. The fitting comprises a first segment disposed outside the filter and incorporating a fuel line receiving aperture and a second, mating segment disposed within the filter. The filter segments are ultrasonically bonded to the fabric such that melting material from the segments flows into the interstices of the fabric and mechanically bonds and retains it within the segments of the fitting.
