  • Patent number: 4129106
    Abstract: Vapor lock and fuel vaporization controls for a gasoline fuel supply system for an internal combustion engine having a diaphragm type fuel pump and a carburetor with a fuel bowl havig a float controlled inlet valve; that comprises two one chamber auxiliary fuel vessels, that are located at strategic places in the fuel flow line, to provide automatic gravity feed to the fuel pump inlet and to the inlet of the carburetor fuel bowl even under adverse heat conditions and as the fuel flows by gravity through each of these vessels there will be a suction exerted on the inlet fuel conduct leading to inlet of the vessel, to bring gas and or liquid fuel forward where the gas bubbles are caught in the gas dome at the top side of each vessel where it is held out of the way as the onward flow of liquid fuel gradually condenses the gas.
