ABSTRACT:
A separate reservoir of fuel having sufficient capacity to operate a vehicle for approximately ten minutes is inserted in the line between the fuel pump and the carburetor. A normally opened remote controlled valve is inserted between the reservoir and the fuel pump and which is independently operable by the vehicle owner. A vent is located in the uppermost portion of the reservoir and consists of a float type check valve that is closed by the rising level of fluid urged into the reservoir from the fuel pump. Leaving the valve open allows the vehicle to operate in the normal fashion. The operator closes the normally opened remotely located valve when leaving the vehicle or giving the vehicle to a parking attendant who has limited authority to only park and service the vehicle. Unauthorized use of the vehicle converts the pressurized fuel system into a gravity fuel system with the limited fuel flowing from the reservoir into the engine carburetor until the fuel is exhausted, thereby stalling the engine.
