Fuel guage problem

I have just started my 69 chevelle after dropping the fuel tank for cleaning. The problem is that with approximately a half tank of gas the guage reads far past full. What's up?

Did you disconnect the battery before dropping the tank? If not, you shorted out the sending unit when you reconnected the wires to the tank. How do I know? I did the same thing you did. Be sure to connect the ground wire first then the lead going to the gauge and last the battery.

The battery was disconnected prior to the drop. The needle stiil moves from the full mark with ignition off and then increases with ignition on!

I would check the ground wire for a clean contact with the body. You can check the gauge by connecting two d cell batteries to it. This should show a half full reading if the gauge is still ok.
