sticky fuel gauge

I had my 90SC sitting for a few months w/ a near empty fuel tank. When I got it back on the road the fuel gauge was sticking below the amount of fuel that was in the tank. I think the sending unit in the tank must have collected some rust and is most likely causing the problem. Does anyone know of an additive that might loosen things up so I don't have to pull the tank to fix it?
 
Mine was stuck like that, so I went out to a nice remote country road ouside of town and slammed the car around with some hard runs and cornering and it came loose :D.
