Fuel Gauge
 

Ok, so after putting in a new dash and tach, i went to start it,and after having it run for a while, i noticed that the needle was pegged way past full. so after flipping the tank selector alot and looking through the wires and such, im kinda at a loss. i've browsed thru the older posts and couldn't find anything. and i know it worked an hour before, well cuz i was using then. So any input would be appriceated!
Thanks,
Cole

I had the same issue after installing a carburetor. The gauge itself may be bad, or perhaps a round plug on the firewall just to the driver's side of the intake manifold may have come unplugged. That was my problem.
Other than that, maybe there is an issue with the printed circuit? I'm sure someone else will chime in with further advice.

that usally is the sender unhooked

Re: Fuel Gauge
 

One of your sending wires is grounding out somewhere. Check the sending lead from the tank to the gauge. Remove the sending unit ground strap and clean the contact areas and re-attach. Also, you might try taking out the sending unit from the tank, cleaning the contact areas on the tank and sending unit base and re-installing. I had to do that once after checking all other wires.
good luck

Turned out that i had just loosened the plug in the firewall. simple mistake of mine, but thank you!

lucky, i had to drop my tank and re-attach a ground wire to get my gas gauge to stop lying and saying it was past full hahahaha

Problem solved is such a great feeling, especially when you don't have to chase wires.
