I found an ad for a 105 gal Delta fuel tank with a Fill-rite 15gpm pump for less than $500. I called the guy and he said it is bone dry but it smells like it had gasoline in it. Is there any way a person could clean out this tank and pump to make sure there is no more gas in it? I do not want to spend more money than I have to. would I be better off to buy all new or what? Any input would be greatly appreciated.
