An auxiliary fuel metering and transfer control system for an internal combustion engine. The system consists essentially of a pressure vessel for storage of propane, methane, natural gas or a similar gaseous fuel, a pressure regulator for maintaining constant gaseous fuel pressure during operation of the system, a solenoid valve and a magnetic reset safety switch, a metering valve, a transfer valve and an auxiliary fuel nozzle positioned in the Venturi of the carburetor on the engine using the system. The metering valve operates in response to changes in the intake manifold vacuum of the engine and changes in the air velocity in the carburetor of the engine. The transfer valve operates in response to movement of the throttle linkage on the carburetor of the engine. During operation of the engine, the system is substituted for both the idle circuit or system and the acceleration circuit or system of the carburetor.
