Dumb question but can the fuel sending unit be changed without dropping the fuel tank? It looks like the rear end may be too close, I just didn't wan to get into a can of worms. I grounded the sending wire and the gauge works fine, I also cleaned up and replaced the ground strap around the fuel line, so it must be the sending unit.[/QUOT
Yes you can.
Jack the rear up and put jack stands under the fraim rails.
Then lower the jack/rear end.
Now you can get to the sender.
Be careful of sparks when removing the ring.
The use of a brass punch is a good idea,or a sending unit wrench.
Thats it !
