ABSTRACT:
A fuel tank has an outlet fuel line with a valve adjacent the tank. The valve is air operated open and spring biased toward closed. A frangible envelope surrounds the fuel tank and is pressurized from the same air line as that to the valve so loss of air pressure in the envelope leads to closing of the valve in case of a crash situation that causes the envelope to rupture.
