I have cleaned several tanks that had old fuel residue and varnish by sealing all the openings and pouring in a gallon of liquid paint stripper and letting that sit for a few days. Move the tank once in awhile so it gets to all the areas you want to clean. Drain the tank and then rinse with a cleaner such as Simple Green and let dry in the hot sun. Works for me! Eric
