Fuel Guage Issue

Have a class a on a F53 ford chassis. Havent driven it for years but am currently getting it out of mothballs. When I parked it over 6 years ago, the fuel gauge would only rise to 1/4 full with the key on. Didn't matter how much fuel was in the tank, even full. With the key off, it drops to below zero. I know there were lots of problems with these fuel pumps but does this sound like a faulthy sending unit or a wiring issue? My mechanic is now draining the fuel tank as the fuel is over 6 years old. While he has the fuel tank off, I am just curious if replacing the entire fuel pump/sending unit would solve the fuel gauge problem. I would really like to not have to count miles. Any advise would be greatlly appreciated.

That should fix the issue it's one unit also have him replace any and all rubber lines, the wiring should be OK they are loomed up and sit on the tank just as long as no critters got into the unit and started chewing
