Gas gauge woes..

Ruger64 said

I dont have the factory clip thing. I use two small hose clamps and a copper wire. Thats the way I did it before and worked fine. I didnt get a chance to go in the garage today. I put exactly 7 gallons of fuel in it. It holds 16. I even pulled on tge copper wires. The clamps are holding the wire ends really tight. I guess I will take them off and maybe inspect them. My fuel line is even new. I am lost.

It's not at all clear to me what you have actually checked?

Did you ground the sender wire, or not, and what happened?

If the gauge deflects to full with the sender wire grounded, then the gauge/ wiring is most problably OK.

As Red said, check the sender connector. The wire can break right there in the connector.

If that checks out, take your meter and measure the resistance/ continuity of the tank sender. Check resistance/ continuity from the sender supply tube to body ground.

Approximate sender resistances are:

L = 73.7 Ohms (empty)
M = 23.0 Ohms (1/2)
H = 10.2 Ohms (full)
