Abstract: A fuel system of the gaseous type utilizing the gas such as propane, methane or the like, wherein gas, preferably in liquefied form, in a tank carried in the trunk compartment of a car, for example, is taken from the tank in gaseous form and conveyed to the intake manifold of the internal combustion engine of the car at very low pressure, through a feeder gasket installed between the carburetor and the intake manifold. Thus it does not require modification of the existing carburetor or replacement thereof, and when installed for alternate use with an existing conventional type gasoline fuel system, means are employed for selectively switching from one system to the other.
