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.

First claim

The invention claimed is:

1. 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.

2. The process of claim 1 , wherein the several friction tabs that are included in the band are arranged to lie in circumferentially spaced-apart relation about and in engagement with the curved exterior surface of the fuel filler pipe, the band also includes several coating bridges, and each of the coating bridges is arranged to interconnect proximal ends of two adjacent friction tabs and lie in radially outwardly spaced-apart relation to a portion of the curved outer surface that extends between a pair of adjacent friction tabs.

3. The process of claim 2 , wherein one of the coating bridges of the band comprises an upper segment coupled to a proximal end of one of the friction tabs and a separate lower segment coupled to a proximal end of another of the friction tabs and the fastener is coupled to each of the upper and lower segments.

4. The process of claim 3 , wherein the upper segment includes an inner section that is curved and connected to the proximal end of one of the friction tabs and an outer section that is flat and is coupled to the fastener and wherein the lower segment includes an inner section that is curved and connected to the proximal end of one of the another of the friction tabs and an outer section that is flat and is coupled to the fastener.

5. The process of claim 2 , wherein the band of the friction-fit pipe mount includes a top strap, a bottom strap arranged to lie in side-by-side mating relation to the top strap, and a loop that interconnects the top and bottom straps and is formed to include the friction tabs and portions of the coating bridges, and the fastener is coupled to the top and bottom straps to block movement of the bottom strap relative to the top strap and to tighten the loop to lie in a stationary position wrapped around and in engagement with the curved exterior surface of the fuel filler pipe.

6. The process of claim 5 , wherein the top strap comprises an inner section that is curved and connected to the proximal end of one of the friction tabs and an outer section that is flat and coupled to the fastener.

7. The process of claim 6 , wherein the bottom strap comprises an inner section that is curved and connected to the proximal end of one of the another of the friction tabs and an outer section that is flat and is coupled to the fastener.

8. The process of claim 7 , wherein the filler-pipe anchor bracket further includes a mount-support flange coupled to the outer sections of the top and bottom straps.

9. The process of claim 5 , wherein the bottom strap comprises an inner section that is curved and connected to the proximal end of one of the friction tabs and an outer section that is flat and coupled to the fastener.

10. The process of claim 5 , wherein the filler-pipe anchor bracket further includes a mount-support flange coupled to free ends of the top and bottom straps to locate the fastener between the loop and the mount-support flange and adapted to mate with a vehicle frame to support the fuel filler pipe relative to the vehicle frame to communicate with a vehicle fuel tank associated with the vehicle frame.
