Abstract
A fuel tank fill assembly includes a fuel fill tube adapted to be coupled to a fuel tank and configured to receive fuel discharged by a pump nozzle. The assembly includes a tube mounting bracket for mounting the fuel fill tube in a stationary position in a vehicle to conduct fuel to the fuel tank. A process for coating the tube mounting bracket is disclosed.
Claims10
A process for providing a fuel tank fill assembly, the process comprising the steps of
- mounting a filler-pipe anchor bracket on a fuel filler pipe using a friction fit to produce an uncoated fuel-delivery conduit and to establish several dual-coat flow gaps between the fuel filler pipe and the filler-pipe anchor bracket, the mounting step comprising the steps of engaging a friction-fit pipe mount included in the filler-pipe anchor bracket to a curved exterior surface of the fuel filler pipe to form several dual-coat flow gaps between the curved exterior surface of the fuel filler pipe and an opposed inner surface of the friction-fit pipe mount, the engaging step comprising the steps of
- wrapping a band included in the friction-fit pipe mount and formed to include several friction tabs around the curved exterior surface of the fuel filler pipe and coupling a fastener included in the friction-fit pipe mount to the band to tighten the friction-fit pipe mount around the curved exterior surface of the fuel filler pipe to establish a friction fit between free ends of the friction tabs and the curved exterior surface of the fuel filler pipe to hold the band in a stationary position surrounding a portion of the fuel filler pipe so as to form the several dual-coat flow gaps between the curved exterior surface of the fuel filler pipe and inner surfaces of the band and friction tabs that provide the opposed inner surface of the friction fit pipe mount and
- applying a multi-layer protective coating to exposed portions of the friction-fit pipe mount and the fuel filler pipe included in the uncoated fuel-delivery conduit after the mounting step, the applying step including the steps of first introducing a first coating material into the dual-coat flow gaps to establish a first coating layer located in the several dual-coat flow gaps and adhered to the curved exterior surface of the fuel filler pipe and the opposed inner surface of the friction-fit pipe mount and then second introducing a second coating material into the several dual-coat flow gaps to establish a second coating layer on exposed portions of the first coating layer located in the several dual-coat flow gaps so that multi-layer protective coating is present in the several dual-coat flow gaps on portions of the curved exterior surface of the fuel filler pipe and the opposed inner surface of the friction-fit pipe mount that cooperate to define a boundary of the several dual-coat flow gaps.
