Abstract
A fuel injection system for engines and, in particular, internal combustion engines used on marine vessels, is disclosed including a fuel injection system having a supply port for receiving fuel at a rate in excess of the controlled rate, an injection port for discharging fuel into the engine at the controlled rate and a return port for conducting fuel in excess of that discharged from the injection port from the injection system. The fuel injection system also includes a pump having an inlet directly connected by a first conduit to a return port and an outlet directly connected by a second conduit to the supply port, a third conduit system for conducting fuel from the supply tank into the first conduit at a first location between the return port and the inlet, and a pressure regulating system for maintaining the pressure at the return port at a predetermined substantially constant super-atmospheric pressure.
