Re: Fuel guage acting GOOFY!
Mine does the same... Ive traced all the wires except where they go thru the rear hump into the tank.. So at least in my case, maybe yours, the sending unit is bad or a loose connection. IIRC full tank means no ground. But dont hold me to that..

Here’s how to check the sender:
Remove the sender wire going to the gage.
Connect an ohmmeter between ground to that wire.
A correct reading will be between zero and 90 ohms.
With 2 gallons in the tank the reading should be much closer to 0 ohms.
