ABSTRACT OF THE DISCLOSURE A fuel injection system of an outboard motor is provided with a vapor separator as a fuel tank disposed in the outboard motor and the system includes a fuel return pipe connected to the vapor separator, a fuel supply pipe connected to the vapor separator for supplying fuel to the fuel injector and a vent means connected to the vapor separator. The vent means is connected to a port formed to the throttle body through a connection hose on an upstream side of the throttle valve. The port formed to the throttle body is opened at a portion at which an air flows in the throttle body with highest flowing speed and upstream and downstream sides of the throttle valve are communicated through a by-pass passage which is provided with a port on the upstream side of the throttle valve opened near the port formed to the throttle body. In another aspect of the vapor separator, the fuel return pipe has one end opened to an interior of the vapor separator at a portion below a surface level of fuel stored in the vapor separator and the vapor separator is provided with a bottom portion outwardly projecting. The fuel supply pipe has one end opened to the interior of the vapor separator at a projected top end of the bottom portion.
