Abstract: A new and improved fuel vaporization and delivery system for vaporization of gasoline from the fuel line of an internal combustion engine and for delivery of fuel in the vapor state to a conventional carburetor or into an air stream at the intake manifold to afford increased exposure of the fuel in the fuel air mixture for complete combustion and utilization of fuel. The invention incorporates self regulatory features, stages and materials to match the chemical and thermodynamic properties of gasoline while maintaining a safe margin below the flash point of gasoline.
