So true. Gas will leak it a big way through a hole that holds water. I use a funnel to filter fuel that passes gas at a high rate but not a single drop of water. When looking for a leak, use an 18 to 24 inch length of small diameter hose. Place one end in your ear and pass the other end over seams and areas of the tank you suspect may contain a leak. With 2 or 3 pounds of air pressure in the tank, a leak is hard to miss. It will put a very noticeable hiss in your ear. Larry Flesner
