The gauge is a balancing act with one coil always pulling the needle toward full and one toward empty. Since it always wants to jump to full I would look for a wire or ground issue -- maybe wire is broken somewhere and intermittently makes contact or maybe there is a poor crimp connection or the tank ground is questionable.
Since it works at times, if it is in the gauge it might be because somehow the sender terminal on the back of the gauge was twisted when tightening the wire. That could have caused an issue with the connection inside. Mechanical binding after a severe jolt is always possible and I suppose it is equally possible since the car is converted that the gauge was exposed to 12v and somehow the coil was burned or a core permanently magnetized. If that is the case I would think it would always read incorrectly.
