I gave the truck to my father and he returned it several years ago when he was no longer able to drive it. The fuel gauge needle constantly moves, it doesn't stay at one point. At first I thought this might be a condenser but the needle does this even when the engine isn't running (key on of course). I replaced the condenser in the distributor and that did not solve the problem. Anyone have any ideas about this? 1953 Chevy 3100 fuel gauge - youtube video

Follow it to where the other end of the wire which should make contact with the bottom of the cab under the driver seat. That is the factory correct location for it. Remove the nut and bolt and clean the metal for a good ground. That is where I would start.

I spent most of my career in instrumention of some sort and don’t remember ever seeing it. The gauge needle is going full tilt to both pegs and very quickly at that. This makes me think that you might have a ‘dirty’ supply voltage if the truck was running.
I would troubleshoot the problem by first disconnecting the sender wire at the gauge. With key on, if the problem goes away you know where to start looking. If it stays, I would remove the (+) side wire and use a battery charger clipped to the (+) side of gauge and negative side of charger to gauge housing. If problem is gone then it’s in your voltage supply wire or gauge ground. If it stays then your in the market for a new gauge. Good luck
