Abstract

A fuel pump module including a fuel reservoir, a fuel pump communicating with the fuel reservoir and having a fuel outlet, and a fuel filter assembly movably coupled to the fuel reservoir to facilitate installation of the fuel pump module into a fuel tank. The fuel filter assembly communicates with the fuel outlet to filter fuel that has passed through the fuel pump. In one aspect of the invention, the fuel filter assembly is pivotally movable with respect to the reservoir. In another aspect of the invention, the fuel filter assembly is linearly movable with respect to the reservoir.

Claims

1. A fuel pump module comprising:

a fuel reservoir;

a fuel pump communicating with the fuel reservoir and having a fuel outlet; and

a fuel filter assembly movably coupled to the fuel reservoir to facilitate installation of the fuel pump module into a fuel tank, the fuel filter assembly communicating with the fuel outlet to filter fuel that has passed through the fuel pump.

2. The fuel pump module of claim 1, wherein the fuel filter assembly is movable with respect to the reservoir from an installing position, wherein the fuel pump module can be installed into the fuel tank, to an operating position, wherein the fuel pump module is supported inside the fuel tank.

3. The fuel pump module of claim 2, wherein the fuel filter assembly is pivotally movable from the installing position to the operating position.

4. The fuel pump module of claim 3, wherein the fuel filter assembly includes an extension member that is pivotally mounted to the reservoir.

5. The fuel pump module of claim 2, wherein the fuel filter assembly is linearly movable from the installing position to the operating position.

6. The fuel pump module of claim 5, wherein the fuel filter assembly includes an extension member that is linearly movable with respect to the reservoir.

7. The fuel pump module of claim 6, wherein the reservoir includes an outer wall having therein a groove for slidably receiving the extension member.

8. The fuel pump module of claim 7, wherein the extension member is substantially T-shaped in cross-section and wherein the groove includes a transverse slot that substantially constrains the extension member to linear movement when the extension member is received in the groove.

9. The fuel pump module of claim 2, further including a fuel level sensor for sensing the amount of fuel in the fuel tank.

10. The fuel pump module of claim 2, further including a flange connected to the reservoir for closing the fuel tank when the fuel pump module has been installed in the fuel tank.

11. The fuel pump module of claim 10, wherein the flange includes an outlet port communicating with the fuel filter assembly to allow filtered fuel to exit the fuel tank.

12. The fuel pump module of claim 11, wherein the fuel filter assembly communicates with the outlet port via a conduit extending between the outlet port and an outlet on the fuel filter assembly.

13. The fuel pump module of claim 12, wherein the reservoir includes a conduit channel for retaining the conduit.

14. The fuel pump module of claim 1, wherein the fuel filter assembly communicates with the fuel outlet via a conduit extending between the fuel outlet and an inlet on the fuel filter assembly.

15. The fuel pump module of claim 14, wherein the reservoir includes a conduit channel for retaining the conduit.

16. The fuel pump module of claim 14, wherein the conduit is a flexible tube.

17. A fuel pump module comprising:

a fuel reservoir;

a fuel pump communicating with the fuel reservoir and having a fuel outlet;

a fuel filter assembly coupled to the fuel reservoir and movable with respect to the fuel reservoir to facilitate installation of the fuel pump module into a fuel tank, the fuel filter assembly being movable between an installing position, wherein the fuel pump module can be installed into the fuel tank, and an operating position, wherein the fuel pump module is supported inside the fuel tank, the fuel filter assembly communicating with the fuel outlet via a conduit to filter fuel that has passed through the fuel pump; and

a flange connected to the reservoir for closing the fuel tank when the fuel pump module has been installed in the fuel tank, the flange including an outlet port communicating with the fuel filter assembly via a conduit to allow filtered fuel to exit the fuel tank.

18. A method of installing a fuel pump module in a fuel tank having an opening, the fuel pump module having a reservoir and a fuel filter assembly movably coupled to the reservoir, the method comprising:

positioning the fuel filter assembly in a first position relative to the reservoir;

inserting the fuel filter assembly into the fuel tank through the opening;

inserting the reservoir into the fuel tank through the opening; and

moving the fuel filter assembly with respect to the reservoir to a second position, thereby allowing the reservoir to be fully inserted into the fuel tank.

19. The method of claim 18, wherein inserting the reservoir into the fuel tank causes the moving of the fuel filter assembly with respect to the reservoir.

20. The method of claim 18, wherein inserting the reservoir and moving the fuel filter assembly occur substantially simultaneously.

21. The method of claim 18, wherein moving the fuel filter assembly includes pivoting the fuel filter assembly with respect to the reservoir.

22. The method of claim 18, wherein moving the fuel filter assembly includes linearly moving the fuel filter assembly with respect to the reservoir.

23. The method of claim 18, further including:

aligning the reservoir with the opening after inserting the fuel filter assembly into the fuel tank and before inserting the reservoir into the fuel tank, such that the fuel filter assembly moves laterally inside the fuel tank.

24. The method of claim 18, further including:

sealing the opening with a flange after the reservoir is inserted into the fuel tank.
