Some cars do now have a roll over valve to shut the gas off if the car flips. Also it is a USCG requirement that a check valve be installed at the tank on a gas engined boat. What is the drawback of a check valve on an aviation engine. I understand that it is one other piece in the fuel system that could cause a power loss but it would be a great safeguard in a crash. I suppose the tank would rupture if the crash was severe enough and a fuelcell could help that. I think I heard someone say planes are not built to crash.
