I have a 31 aluminum work boat with an under deck fuel tank which must be
leaking. The aluminum deck is welded in place. The tank is a 100 gallon
aluminum tank. The boat is only 1 year old. I removed the drain plug from
the back of the boat and about 2 gaollons of gas came out, this leads me to
believe that the crack must be on the top of the tank because the tank is
almost full and this is the only time I ever opened the drain plug. Before I
do any work I want to make sure I don't have an explosion. If I fill the
bilge area with dishsoap and water and then drain it will this remove all
dangerous vapours? Any other ideas?
