ABSTRACT A marine fuel injection system for a two cycle crankcase compression internal combustion engine includes a puddled fuel return line having an outlet in the excess fuel return line from the fuel injector and pressure regulator to the vapor separator and high pressure fuel pump for recirculation. Excess fuel return flow creates a vacuum at the outlet of the puddled fuel return line to suction puddled fuel there- through for recirculation together with the excess fuel to the fuel pump. The end of the puddled fuel return line at the outlet extends within and parallel to the excess fuel return line to occupy a portion of the cross sectional area of the latter to reduce such cross-sectional area and create a venturi in the excess fuel return line at the outlet of the puddled fuel return line.
