We're cleaning out junk piles and we have a 500 gallon fuel tank that hasn't been used in over ten years. Roughly 40" in diameter and 60" long. Asking $50 or so. Its rusty but no fuel smell anymore. Ill have pictures later tonight. If it isn't taken its going for scrap soon. I hate to see it go to waste. Located about an hour south of Springfield and an hour northeast of st Louis.
