The sending unit for the gas tank is cheap and easy to replace. Why not just fix it?

Also.. check the sending unit ground at the tank. I'm willing to bet a bad ground is your problem.

When I picked up my Jeep, the ground wire was dangling. I hooked it up, and my mileage was so bad I thought it still had to be bad. It wasn't, my mileage was really that bad.

Fuel tank capacity.

Measure and multiply length x width x height and divide that result by 231 and that will be the capacity of your tank in gallons.

It all depends on how heavy my foot gets. Usually around 20 mpg. I have a 258 in my CJ5.
