Sometimes you do. If the new fuel pump came with a substitute harness you will need to. The reason is that a change has occurred possibly due to a recall and the old harness won't fit the replacement pump.
On this model the fuel pump is in the fuel tank. You'll have to drop the fuel tank to replace it. In order to maintain the warranty on the new fuel pump, you'll also have to replace the strainer. It is also recommended that you replace the wiring harness connected to the fuel pump at the same time.
On these vehicles, the wire harness to the fuel pump/ sending unit goes bad. Replace with a new updated pigtail wiring harness. The fuel tank must be removed from the vehicle to accomplish this.
It is in the gas tank . When you replace the fuel pump it is a good idea to replace the wiring harness as well-a lot of times they are faulty tou mind as well replace it since you have to drop the tank anyways.
The fuel injectors on a 2003 VW Tdi are replaced by disconnecting the wiring harness, fuel supply, and removing the retaining bolts. They can then be pulled from the fuel rail and replaced.

The term "harness" refers to the wiring loom. The fuel pump harness would be the wiring to the fuel pump assembly. That wiring would be part of a much greater wiring loom, that would run along the frame rail, and immerge under the hood to become part of the main engine control wiring harness assembly, which includes all the wiring to all the engine sensors and solenoids, and even runs to the computer. You can locate one end of the harness where the connector plugs into the fuel pump on top of the fuel tank. It will go from there, and pretty much run the length of the car, spidering out under the hood, and going just about everywhere. There may be a connector or connectors that separate the rear body and fuel pump harness from the rest of the vehicle harnesses, but don't count on it.
It's located in the gas tank which has to be lowered to replace the pump.
Remove the instrument panel cover from your 2002 Subaru. Remove the fuel gauge retaining screws. Remove the wiring harness from the back of the fuel gauge. Reverse the process to install your new fuel gauge.
