I have fabricated many fuel tanks for myself and others(5052 H32 aluminum- we are fabricators), and have zinc chromated them, properly ventilated, etc..In salt water exposure, they still pit and corrode if salt water is in contact for very long. Last winter I built a new fuel tank for one of my boats (four boat theory) and had the local Line X it dealer coat this tank (used on pickup beds). Cost me $100.00 for a 120 gallon tank. I am very happy with it.
