Is the a fuse for the gas gauge in a 1966 Valiant?
The gauge reads emptyWhat is the issue?
You can get a wiring diagram from mymopar.com or classiccarwiring.com
And trace out the circuits.
IIRC the feed for the guages comes from the ignition switch which gets unfused power from the splice.
Yes temp gauge works fineHave you determined it's not the sender or the wiring?
Does your temp gauge work?
Thank you I'll try that tomorrowThe sending unit needs to be grounded by way of a ground strap from the sending unit hose neck to the hard line that heads to the engine. It needs to be clean metal, and a nice tight clamp. Most of the time that is the problem, but you can check the guage by grounding the sending unit itself by sticking a test light prong into the sending unit plug and grounding the other end to good ground. If the guage is working, it will go to full, but you don’t need to let it get that far, just ground it and have somebody watch to see if it climbs. If it does, get the sending unit grounded and you should be good to go.
Expect from full to 1/2 tank the gauge will show fullDon't get your hopes up just yet, for gauge accuracy, at least
