Abstract
A marine fuel injection system for a two cycle crankcase compression internal combustion engine includes a puddled fuel return line (44) having an outlet (44b) in the excess fuel return line (43) from the fuel injector (24) and pressure regulator (26) to the vapor separator (33) and high pressure fuel pump (25) for recirculation. Excess fuel return flow creates a vacuum at the outlet (44b) of the puddled fuel return line (44) to suction puddled fuel therethrough for recirculation together with the excess fuel to the fuel pump (25). The end (44d) of the puddled fuel return line (44) at the outlet (44b) extends within and parallel to the excess fuel return line (43) 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 (43) at the outlet (44b) of the puddled fuel return line (44).
