Helped a friend pull his gas tanks last Sunday. This GMC had sat for 11 years, and ended up with a coating of a gooey gunk on the tank bottom. Then rust up above the bottom. So I told him to used a Hotsy to clean the inside by way of the tank sender opening. Worked very well. Then put vinegar in for two days. During that time. Shook the tank around. Then a power washer. How need to use a small fan to blow air into it for a few days. Looking really good. Bob Dunahugh
