Hello,

The fuel pump ground is shared with the fuel pump relay. It is located at the left front of the engine.

See image below.

Hope this helps.

Cheers, Boris

Hello,

The fuel pump is grounded to the chassis. You will have to trace the black/white wire to find the ground. It should be located on the left front of the engine compartment.

I have attached the wiring schematic below for your reference.

Let me know of any questions.
Thank you.

I have replaced the fuel pump, but I don't remember where the ground wire was attached to the vehicle.

Hello,

The ground for the fuel pump is located on the left top front of the engine block.

I have attached wiring schematics and diagram below for your reference.
It will be a black/white wire.

Let me know of any questions.
Thank you.

The fuel pump ground wire is only 6 or 7 inches long.
The engine block is several feet from the fuel pump.

Are you talking about the ground wire that came with a replacement fuel pump? Can you upload a picture?

Yes, the ground wire from the fuel pump assembly.

You can actually ground it to any good spot. You can also splice a longer wire to the ground, so it will allow you to reach an ideal ground spot.
