## Abstract

An in-tank fuel pump assembly may have a mounting flange with a plurality of first couplings, a fuel pump, a carrier connected to the fuel pump, a plurality of second couplings 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 couplings to locate the pump relative to the mounting flange.

## Claims

### Claim 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
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 supports are coupled to both the first coupling features and the second coupling features to locate the fuel pump relative to the mounting flange.

### Claim 2 (depends on 1)

The assembly of claim 1 wherein the supports are connected to the coupling features without any fasteners.

### Claim 3 (depends on 2)

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.

### Claim 4 (depends on 1)

The assembly of claim 1 wherein the fuel pump includes a coupling feature and a support is coupled to the fuel pump at one end and to the mounting flange at the other end.

### Claim 5 (depends on 4)

The assembly of claim 4 wherein fuel flows through the fuel pump coupling feature and the support, and wherein the flange includes a passage communicated with the fuel pump coupling feature via the support.

### Claim 6 (depends on 1)

The assembly of claim 1 wherein the supports are tubular bodies and the coupling features includes one or both of protrusions over which the supports are fitted, and cavities into which the supports are fitted.

### Claim 7 (depends on 1)

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.

### Claim 8 (depends on 7)

The assembly of claim 7 wherein the three supports are not aligned with each other.

### Claim 9 (depends on 1)

The assembly of claim 1 wherein at least one support and associated coupling feature 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.

### Claim 10 (depends on 1)

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.
