Fuel pump assembly with removable and/or movable supports
An in-tank fuel pump assembly may have a mounting flange with a plurality of first coupling features, a fuel pump, a carrier connected to the fuel pump, a plurality of second coupling features on at least one of the carrier and the fuel pump, and a plurality of supports each connected to one or the first and second coupling features to locate the pump relative to the mounting flange. In some embodiments, at least one coupling feature is movable.
1. A fuel pump assembly, comprising:
a mounting flange including multiple first coupling features;
a fuel pump supported by the mounting flange;
a carrier coupled to the fuel pump and to the mounting flange; and
multiple rigid tubular supports, each support being coupled between the mounting flange and at least one of the carrier and the fuel pump, wherein both the carrier and fuel pump include second coupling features and each support is coupled to both one of the first coupling features and one of the second coupling features to locate the fuel pump relative to the mounting flange, and wherein fuel flows through the second coupling feature of the fuel pump, the support coupled to said coupling feature and through a passage included in the flange communicating with the second coupling feature of the fuel pump.
2. The assembly of claim 1 wherein the supports are connected to the coupling features without any fasteners.
3. The assembly of claim 2 wherein the supports are pressed onto the coupling features with an interference fit or a friction fit provided between them.
4. The assembly of claim 1 wherein the coupling features include one or both of protrusions over which the supports are fitted, and cavities into which the supports are fitted.
5. The assembly of claim 1 wherein three or more supports are provided, each support being coupled to the mounting flange at one end and to the fuel pump or the carrier at the other end.
6. The assembly of claim 5 wherein the three supports are not aligned with each other.
7. The assembly of claim 1 wherein at least one support and one of the coupling features coupled to said at least one support comprises a tube with a sidewall with a recess therein and a pin received in the tube and with a dog extending into the recess.
8. The assembly of claim 1 wherein the supports are connected to the coupling features with at least one of adhesives, threads, welds, clamps, molded snaps or molded locking elements.
9. The assembly of claim 1 wherein at least one support is rigidly coupled to both one of the first coupling features and one of the second coupling features to inhibit or prevent movement of the carrier toward or away from the mounting flange.
10. The assembly of claim 1 wherein at least one support is fixed to both one of the first coupling features and to one of the second coupling features so that there is no relative movement between the support and the first coupling feature and there is no relative movement between the support and the second coupling feature.
11. A fuel pump assembly, comprising:
a mounting flange including multiple first coupling features;
a fuel pump supported by the mounting flange;
a carrier coupled to the fuel pump and to the mounting flange; and
tubular supports coupled between the mounting flange and at least one of the carrier and the fuel pump, wherein at least one of the carrier and fuel pump includes second coupling features and the tubular supports are coupled to both the first coupling features and the second coupling features to locate the fuel pump relative to the mounting flange and wherein at least one of the second coupling features is movable relative to the carrier or fuel pump to which the at least one movable second coupling feature is attached.
12. The assembly of claim 11 wherein one of the supports is substantially straight and is coupled to said at least one movable second coupling feature.
13. The assembly of claim 11 wherein multiple second coupling features are movable.
14. The assembly of claim 11 wherein at least one movable second coupling feature rotates or pivots relative to the carrier.
15. The assembly of claim 14 wherein at least one movable second coupling feature rotates about an axis that is not parallel to an axis of the connection between the at least one movable second coupling feature and the support that is connected to the at least one movable second coupling feature.
16. The assembly of claim 11 wherein the carrier includes a slot and the movable second coupling feature is slidably received in the slot.
17. The assembly of claim 11 wherein a central axis of the fuel pump is not parallel to a central axis of the mounting flange.
18. The assembly of claim 11 wherein at least two second coupling features are movable and said supports include two supports that are each straight and each of which is coupled to a different movable second coupling feature, where the straight supports are supports that have ends not inclined by more than 10 degrees relative to each other.
19. The assembly of claim 11 wherein the at least one movable second coupling feature is a protrusion over which the support is fitted or a cavity into which the support is fitted.
20. The assembly of claim 19 wherein at least one support is press-fit into or over the movable second coupling feature such that there is no relative movement between the at least one support and the movable second coupling feature.
