Marine fuel tanks are constantly exposed to the elements compromising fuels’ useful integrity. cool water against a boat’s hull transfers temperatures that differ from the surrounding air causing condensation to quickly accumulate at the bottom of the tank. It is always best to keep fuel tanks full to decrease the tanks’ airspace. as this is not always an option. prolonged tank wall exposure can result in a ruined family weekend or loss of crew efficiency.
