One of the hurdles in getting my bus on the road is my gas tank. Since it hasn't been used in 10+ years I need to clean it out before using it so I can avoid changing my fuel filter every 100 miles for the next three years. I have heard of people having their gas tanks "boiled out" but have no idea what is involved in that process. I stopped by the local custom shop and they said they just flush them out with a garden hose. Seems to me there should be more to it than that. Can anyone offer any insight? -Dan
