Abstract

A mount for a level sensor assembly in a fuel tank may include an interconnect member adapted to couple a first tube to a second tube to permit fuel flow through the first tube, the interconnect member and the second tube. The first tube is adapted to be in fluid communication with a fuel pump and the second tube is in fluid communication with fuel in the fuel tank. A bracket is coupled to the interconnect member and adapted to carry at least a portion of the level sensor assembly. In this way, the level sensor assembly may be coupled to fluid tubes associated with the fuel pump, or other tubes, as desired.

Claims (33)

1. A mount for a fuel level sensor assembly in a fuel tank having a fuel pump, the fuel pump configured to draw fuel through first and second tubes in the fuel tank, the mount comprising:

an interconnect member having a through passage configured to couple one end of the first tube to one end of the second tube to permit fuel flow through the first tube, the through passage of the interconnect member and the second tube, wherein another end of the first tube is configured to be in fluid communication with the fuel pump and another end of the second tube is configured to be in fluid communication with fuel in the fuel tank;

a bracket carried by the interconnect member and configured to carry at least a portion of the fuel level sensor assembly; and

at least one of the first and second tubes disposing the fuel level sensor assembly in a predetermined position relative to a top or bottom wall of the fuel tank.

2. The mount of claim 1 wherein the at least a portion of the level sensor assembly includes a housing in which a variable resistor assembly is received, and the housing is coupled to the bracket.

3. The mount of claim 2 wherein the housing includes a key and the bracket includes a mating surface to couple the housing to the bracket.

4. The mount of claim 1 wherein the interconnect member has a body portion with a first end for coupling to the first tube, a second end for coupling to the second tube and the through passage is in communication with both the first tube and the second tube to permit fluid flow between the first tube and the second tube by way of the through passage.

5. The mount of claim 4 wherein at least one of the first end or the second end includes retention features to retain thereon its associated one end of the first tube or the second tube.

6. The mount of claim 5 wherein the retention features include outwardly extending barbs configured to engage an inner surface of said associated first tube or second tube.

7. The mount of claim 1 wherein the bracket and interconnect member are integrally formed from the same piece of material.

8. The mount of claim 1 wherein flanges interconnect the bracket and the interconnect member.

9. An apparatus for a fuel tank having a fuel pump, the fuel pump configured to draw fuel through first and second tubes in the fuel tank, the apparatus comprising:

a mount having an interconnect member with a through passage configured to couple one end of the first tube to one end of the second tube wherein fuel may be communicated through the first tube, second tube and through passage of the interconnect member, wherein another end of the first tube is configured to be in fluid communication with the fuel pump and another end of the second tube is configured to communicate with fuel in the fuel tank; and

a fuel level sensor assembly is carried by the mount wherein coupling the mount to the tubes positions the fuel level sensor assembly relative to a top or bottom of the fuel tank.

10. The apparatus of claim 9 wherein the fuel level sensor assembly includes a housing in which a variable resistor assembly is received, and the housing is carried by the mount.

11. The apparatus of claim 9 wherein the interconnect member has a body portion with a first end for coupling to the first tube, a second end for coupling to the second tube and the through passage is in communication with both the first tube and the second tube to permit fluid flow between the first tube and the second tube by way of the through passage.

12. The apparatus of claim 11 wherein at least one of the first end or the second end includes retention features to retain thereon its associated one end of the first tube or the second tube.

13. A fuel tank assembly, comprising:

a fuel pump assembly, comprising:

a fuel pump for pumping fuel;

one end of a first tube through which fuel is provided to the fuel pump, the first tube arranged upstream of the fuel pump in the fuel tank assembly;

a mount coupled to another end of the first tube, the mount arranged upstream of the fuel pump in the fuel tank assembly; and

a level sensor assembly carried by the mount so that the level sensor assembly is carried by the first tube in a predetermined position relative to a top or bottom wall of the fuel tank.

14. The fuel tank assembly of claim 13 further comprising a second tube in communication with fuel in the fuel tank and wherein the mount comprises an interconnect member having a through passage and configured to couple the first tube to the second tube so that fuel may be communicated through the first tube, the through passage of the interconnect member and the second tube.

15. The fuel tank assembly of claim 14 wherein the interconnect member comprises a body portion having a first end and a second end, wherein the first end is coupled to the interior of the first tube and the second end is coupled to the interior of the second tube.

16. The fuel tank assembly of claim 13 wherein the mount is coupled to the exterior of the first tube.

17. A method of installing a fuel level sensor assembly in a fuel tank, comprising the steps of:

determining a desired orientation of the fuel level sensor assembly in the fuel tank relative to a top or bottom of the fuel tank;

coupling a through passage of a mount for the fuel level sensor assembly to one end of a first tube according to the determination, the mount configured to carry at least a portion of the fuel level sensor assembly;

coupling the through passage of the mount to one end of a second tube whereby fluid flows through the first tube, the through passage of the mount and the second tube to a fuel pump inside the fuel tank; and

at least one of the tubes disposes the fuel level sensor assembly in the predetermined position relative to the top or bottom of the fuel tank.

18. The method of claim 17 wherein determining the desired orientation of the fuel level sensor assembly includes determining an angular position with respect to the first tube.

19. The method of claim 17 further comprising determining the desired spatial location of the fuel level sensor assembly within the fuel tank, wherein determining the spatial location includes determining the distance of the fuel level sensor assembly from the bottom of the fuel tank.
