Abstract:
1. A process of assembling a portion of a fuel tank filler neck, the process comprising the steps of providing a tubular housing made of a first plastics material and formed to include a fuel-transfer channel extending from a downstream end thereof to an upstream end thereof, mounting an inlet check valve apparatus on the downstream end of the tubular housing to regulate flow of liquid fuel and fuel vapor through an outlet formed in the tubular housing to open into the fuel-transfer channel, providing a tank mount comprising a spud anchor and a fill tube connector spud, the spud anchor comprising a weld ring made of a second plastics material that is different than the first plastics material and an O-ring seal, clamping the spud anchor onto an exterior surface of the tubular housing to locate the spud anchor in a stationary position on the tubular housing to provide a fluid-leak barrier therebetween, and coupling the fill tube connector spud to the spud anchor to form a tank mount configured to provide means for mating with a fuel tank to support the tubular housing in an aperture formed in the fuel tank to position the downstream end of the tubular housing in communication with an interior fuel-storage region formed in the fuel tank and to position the upstream end of the tubular housing outside of the fuel tank to communicate with a fill tube associated with the fuel tank.
