Fuel Pump Ground Location?

[chaseincats]

Hi all -

Wondering if anyone knows where the fuel pump ground wire terminates in the car.  The pump has two wires going into the wiring loom but the service manual says one of them terminates directly to a ground.  Any idea where that hides on a 1978?

Interesting question.  The 76 wiring diagram shows it as close to the license plate light.  Rear of the car somewhere.  Many other things branched in to it.  I have a vague memory of something behind the plastic panel that covers the rear inside of the car, over the tail lights.  I'll bet it's there somewhere.  Easy to check, a few Phillips head screws.  Nice and dry there, a good place for a ground connection.

But if you think you have a bad fuel pump ground you might check the connector by the tank first.  If everything else works.
