Gas gauge

1967 Camaro- Just installed new tank, sender, rear wiring harness. Everything new but gauge. Tank has about 7 gallons in it. Tank reads E. Disconnected the tan wire in the truck connector and grounded and the gauge goes past full. Ground appears to be good to body. I do not have an ohm meter to test. Any thoughts on where to go?

Re: Gas gauge

If you disconnected the tan wire in the trunk and the guage went past full, then the problem is in or directly attached to the fuel tank. One recent poster with this problem found that the locking ring that hold the sender in the tank was off center just enough to ground the sender connection.

Re: Gas gauge

well I can tell you that the problem is (most likely) after that connector in the trunk, the problem is finding it...

when the gauge reads empty that means that it is grounded, so check to make sure the wire is not pinched somewhere, and that the sender is correctly adjusted

and i know there are two connectors there in the trunk, one for the gas gauge, the other is for the backup light, i think it is possible to switch them, but i am not sure

Re: Gas gauge

When you say that the locking ring is off center, do you mean that in tighting it that it went to far an that the ring tab is touching the ground stud where the wire connects? If so, I guess I will have to drop that tank and make sure nothing is touching the ground? Please inform.

Re: Gas gauge

that is EXACTLY what happened to mine......What I did is I left the wires attached to the sending unit, took the lock ring off, turned on the key on, the gauge worked, so i carefully put the ring back on , checked with key still worked, carefully tightened the ring checked with key on still worked.....I did this with the tank out on the ground to make sure it was working before I put tank back up.....hope this helps.

Re: Gas gauge

What a beating! I dropped the tank and backed the ring off a tad and checked the gauge. It appeared to work. Carefully mounted the tank back and put about 6 gallons of gas in and hit the key. Back to E! Can anything else metal wise be grounding this out after you bolt up the tank?

Re: Gas gauge

I got lucky! With the tank mounted, I was able to get a light up in front of the tank to see the ring. Used a screwdriver and lightly tapped the locking ring to move it about 1/4" and the gauge reads correctly now. Thanks for all the help.
