Abstract: An internal combustion engine fuel economizing device is disclosed. A cylinder having an inlet and an outlet is installed between the fuel pump and the carburetor. Fuel discharged from the fuel pump enters the cylinder inlet through an inlet conduit. The fuel stream is filtered by a filtering device located within the inlet conduit. The fuel is concentrated in the cylinder by the fuel pump pressure, and exits the cylinder through an outlet conduit. At the terminus of the outlet conduit is a restricted opening which creates a pressure drop. The pressure drop changes the fuel stream to a liquid-vapor phase which enters the carburetor for mixing with air prior to combustion in the engine.
