fuel gauge problem

I have a 2004 Holiday Rambler Neptune. Lately the fuel gauge at times jumps to full,although the fuel tank is not full. I suspect a poor ground at the sending unit in the fuel tank. I'm new to this, any help would be appreciated

Thanks, Frank

Hello Frank and . We are glad to have you join us here and I am sure you will enjoy the website and forums. Good luck, stay safe and keep us posted.
I suspect you are correct in a loose ground. If you cannot reach the top of the tank easily, you might try adding a good ground to the harness wiring ground conductor. When the tank is reading correctly, you should be able to locate that wire with an ohm meter. Once you have found it, add the ground and let us know the results.

If the ground checks OK a fuel tank sender is quite a common problem.
