Classic/Antique Car Repair: 1975 Chevy El Camino gas tank, hemmings motor news, chevy el camino

Question
I am restoring this truck. This truck has been setting in a back yard for over 5 years. What is the best way to clean out the gas tank? Thank you.

Answer
This is a problem that is made worse with what to do with the gas that comes out of it. If you have a good disposal site then remove the tank and slosh it around before draining. I then use a sloshing compound that I purchase from one of the vendors in Hemmings Motor News. This will seal the inside of the tank and has done a good job for me.
