RE: Water in an aluminum fuel tank

In 1997 we had two-75 gallon diesel tanks replaced on our last boat.** We were told by the tank manufacturer and the insurance companies surveyor*that the new tanks should be*from marine aluminum grade 5052. Aluminum like stainless steel comes in many grades. I'm not sure water in the fuel tanks would be much of an issue. Maybe we'll hear from someone who has an aluminum boat. I believe most aluminum hulls are made form 5052.
