1930 & 1931 gas tanks all hold 11 gallons and fit the same in all 1930 & '31 body style cowls with one exception. In 1931 the gas shutoff valve was moved into the engine compartment, and those gas tanks have a different gas outlet fitting. Also, early to mid 1930 gas tanks use the 1929 oval instrument panel. Some 1930 trucks used 1929 leftover gas tanks until the stock was depleted.
