You could look at the firewall plugs you may have a wonky connection there.

The fuel gauge wire doesnt enter the bulk head connector. It goes down the left side under the kick panel and runs under the wire protector. Then under the back seat and into the trunk. There it goes through the trunk pan to the sender. Its a dark blue wire. There should be a 6 pin connector behind the left kick panel. Look there for issues and also make sure the ground strap is on under the car. It goes from the hard line and bridges the gap where the rubber line is and connects to the sender.

Assuming this is your 66/67 id also check the connection on the back side of the fuel gauge. And also check grounds at the cluster.

The bimetalic 5 volt voltage "regulator" is heating up and sticking on the off side of the cycle is my bet. (better than stuck on the on side)

You can see the silver colored box about in the center of this picture. Its plugged into the purple and blue board.

RalleyeDash?... It's that silver "can" on the circuit board right beside the speedometer. You should be able to get your arm up there and pull it out to change.

No problem.

My bet is a ground problem.

 

[Red eyed cat]

No problem.

Where can I get one of these

Is the temperature gauge working?

Good point, is it just the fuel gauge that dies or the other gauges as well??

Fuel, oil pressure and temperature all use 5 volts.

If the VR is bad, they all show symptoms.

Just the fuel gauge

Then disregard the voltage regulator. It's a gauge, sender or wire issue.

Tighten down the 4 nuts to the left of the voltage limiter. They are your fuel and temp gauges. Make sure they are snug. It may be heating up during you driving it and losing contact.

. Thanks to all I definitely like all the help on this site ,only been a member for a couple of days and best one yet
