ABSTRACT:
A fuel injection system for an internal combustion engine and particularly an outboard motor. The system includes a fuel vapor separator that is disposed on one side of the throttle bodies at the front of the engine. The fuel vapor separator is comprised of a housing assembly having a cover plate in which an integral fuel inlet fitting, an integral fuel outlet fitting, an integral vent fitting and an integral fuel return fitting are formed. The fuel injectors for the engine are disposed on the opposite side of the throttle bodies from the fuel vapor separator and are supplied with fuel through a vertically extending fuel rail. The pressure regulator is positioned at the top of the fuel rail and the fuel rail is directly affixed to the throttle bodies.
