The letters ‘‘MSG’’ stand for ‘‘Manufacturer’s Standard Gage’’ for sheet steel thickness. 2 Tanks over 1514 liters (400 gallons) must be designed with a factor of safety of four on the ultimate strength of the material used with a design head of not less than 1220 millimeters (4 feet) of liquid above the top of the tank. 3 Nickel-copper not less than 0.79 millimeter (0.031 inch) [USSG 22] may be used for tanks up to 114-liter (30-gallon) capacity. 4 Acceptable only for gasoline service. 5 Gasoline fuel tanks constructed of iron or steel, which are less than 5 millimeter (0.1875) inch) thick, must be galvanized inside and outside by the hot dip process.
