If you did and it's still stuck you can replace just the gasoline gauge.
I doubt that anyone would rebuild the gasoline gauge.

The master parts catalog says:
Group # 3.108 Gauge
49-53 Commercial, Utility
54-55 FFC (Flat Face Cowl) Part # 1517169

Partsvoice says the below vendors each have one NOS in stock.

What color is your needle?

I had tried what you suggested and it would not go above 1/4 tank. I followed your suggestion for searching out a NOS gauge and picked one up on ebay for $50.00. The part number you listed is stamped on the face of my original gauge. $50.00 is cheaper than I was quoted to rebuild my original. I was hoping to have them convert it to 12v as part of the rebuild, but they recommended using a "buck converter", but they want $50.00 just for it. I think I'll go with the Runtz. It looks like people use the Buck converter for higher draw items like the heater blower.

Thanks for all the input.
