The Ford Barn

Just finished my car a few months ago, and now I'm pretty sure the gas tank sealer I used 20 years ago is deteriorating. I started having carb leaks and my engine dying for no apparent reason, and now I realize that the float needle was sticking open or closed. After taking things apart, the carb float and shut-off needle were covered with a very sticky film, as were the top side of the throttle plate and the inside of the intake. Carb cleaner cleans is right off, though.

I hate to pull the tank and have to boil it out and repaint it. Is there a way to fill/rock the car/drain/refill multple times to do this? Should I use gasoline or lacquer thinner? Some other substance to quickly dissolve the sealer?

Any ideas? I'm willing to try something first before pulling the tank.

Thanks
