Location: Connecticut | Agree that it's a loose ground. I'll bet that if the car is standing still, it's not jumping around like that. IIRC, it's grounded thru the tank. So I would bet that the sending unit is loose. There is a rubber O-ring that goes between the sending unit and the tank. Verify that that is in place and that it's holding the sending unit firmly against the retainer. Ron |
