I stored a 72 Comet GT for 20 years and had forgotten to drain the gas tank. It had turned to jello.

Jellied/Varnished gas has to be one of the nastiest smells on Earth.

I had something similar happen with an old car sitting for 20 years in the garage. The "jello" gas was nasty smelling and gooey. I took the tank to a radiator repair shop and they dropped the tank into a boiling solution for two weeks to remove all the goo. I then coated the interior anti-rust preservative to make the tank useful again.
