Between the nuts and the resistor. You're trying to make better contact with the resistor.
You can also lightly use a pink pencil eraser to clean off any corrosion without damaging the resistor.

Do all the instrument cluster lamps and other gauges work normally?

Yes, all gauges work. Just have the movement in fuel gauge. Do not know yet if there is a resistor on the original gauge. Have not had it out to find out yet, but intend to soon.

I noticed mine yesterday would move, but it was around a 1/4 tank. After I filled it, no movement, steady at full. Come to think of it, it only moves when it's less full

Have several loose gauges. Quick ohm check [not isolated] mostly confirms the Hatzie post.

My guage moves while driving but it is obviously related to the fuel moving in the tank(moving the bob) because of inclines or bumps on the road etc.
