Abstract

Vehicle fluid conduit systems and protectors for such systems are presented. Fluid conduit systems can include a fuel fill system having a fuel filler tube, a re-circulation tube, and a protector. In some embodiments, the protector can include a protector bracket and a bolting plate that extend around the fuel filler tube and re-circulation tube. The protector can include a strap. The strap can extend between the fuel filler tube and re-circulation tube between two or more protector attachment locations.

First claim

What is claimed is:

1. A vehicle fuel fill system, comprising:
a fuel filler tube configured to allow transfer of fuel into a vehicle fuel storage tank;
a re-circulation tube in fluid communication with the fuel filler tube; and
a protector, comprising:
a protector bracket having a plurality of attachment tabs;
a bolting plate having a plurality of attachment tabs; and
a strap having a plurality of attachment tabs, the attachment tabs positioned between, and directly attached to, the attachment tabs of the protector bracket and the attachment tabs of the bolting plate, the strap being configured to extend between the fuel filler tube and the re-circulation tube.

2. The fuel fill system of claim 1 , wherein the protector substantially covers both the fuel filler tube and the re-circulation tube near a connection between the re-circulation tube and the fuel filler tube.

3. The fuel fill system of claim 2 , wherein the protector bracket and bolting plate form a channel around a portion of the fuel filler tube and re-circulation tube.

4. The fuel fill system of claim 3 , wherein the strap divides the channel into a first region and a second region, the first region being between the strap and the protector bracket and the second region being between the strap and the bolting plate.

5. The fuel fill system of claim 3 , wherein the protector bracket extends in a longitudinal direction to cover the connection between the re-circulation tube and fuel filler tube.

6. The fuel fill system of claim 5 , wherein the strap extends in the longitudinal direction and terminates prior to the connection between the re-circulation tube and the fuel filler tube.

7. The fuel fill system of claim 1 , wherein two or more attachment tabs of the strap are substantially parallel and offset from each other, the strap further comprising a strap transition extending between the two or more offset attachment tabs.

8. The fuel fill system of claim 1 , wherein the protector further comprising a plurality of fasteners that extend through apertures defined in the attachment tabs of the protector bracket, the attachment tabs of the bolting plate, and the attachment tabs of the strap.

9. A vehicle fuel fill system, comprising:
a fuel filler tube configured to allow transfer of fuel into a vehicle fuel storage tank;
a re-circulation tube in fluid communication with the fuel filler tube; and
a protector, comprising:
a protector bracket having a plurality of attachment tabs;
a bolting plate having a plurality of attachment tabs; and

a strap having a plurality of attachment tabs, the attachment tabs positioned between the attachment tabs of the protector bracket and the attachment tabs of the bolting plate, the strap being configured to extend between the fuel filler tube and the re-circulation tube,
wherein the protector has three fasteners extending in substantially parallel directions, and the strap extends in a generally triangular shape between each of the three fasteners.

10. A protector for a vehicle fluid conduit system, the protector comprising:
a protector bracket having a plurality of attachment tabs;
a bolting plate having a plurality of attachment tabs; and
a strap having a plurality of attachment tabs, the attachment tabs positioned between the attachment tabs of the protector bracket and the attachment tabs of the bolting plate,
wherein the protector bracket and bolting plate are configured to form a cavity substantially all the way around a portion of a first fluid conduit and a second fluid conduit, and the strap is configured to extend between the first fluid conduit and the second fluid conduit within the cavity.

11. The protector of claim 10 , wherein the strap divides the cavity into a first region and a second region, the first region being between the strap and the protector bracket and the second region being between the strap and the bolting plate.

12. The protector of claim 11 , wherein the first fluid conduit is a fuel filler tube and the second fluid conduit is a re-circulation tube.

13. The protector of claim 12 , wherein the protector bracket extends in a longitudinal direction to substantially cover a connection between the re-circulation tube and fuel filler tube.

14. The protector of claim 13 , wherein the strap extends in the longitudinal direction and terminates prior to the connection between the re-circulation tube and the fuel filler tube.

15. The protector of claim 10 , wherein two or more attachment tabs of the strap are substantially parallel and offset from each other, the strap further comprising a strap transition extending between the two or more offset attachment tabs.

16. A method for providing a protector to a vehicle fluid fill system, comprising:
positioning a strap between a first fluid conduit and a second fluid conduit;
bringing together a protector bracket and a bolting plate to form a channel around the first and second conduits such that the strap divides the channel into a first and second region; and
operatively connecting the protector bracket, the bolting plate, and the strap such that attachment tabs of the protector bracket, the bolting plate, and the strap are directed attached to one another.

17. The method of claim 16 , wherein operatively connecting the protector bracket, the bolting plate and the strap includes operatively connecting the protector bracket, the bolting plate and the strap by one or more fasteners.

18. The method of claim 16 , wherein the first fluid conduit extends at least partially through the first region and the second fluid conduit extends at least partially through the second region.
