ABSTRACT:
A fuel supply system for a boat prevents deterioration in engine startability and includes a vapor separator tank arranged to contain fuel at an inner fuel level “P” at a predetermined height, an injector arranged to supply fuel to an engine, and a high-pressure fuel pump that is disposed outside the vapor separator tank and that is arranged to supply the fuel reserved in the vapor separator tank to the injector. The high-pressure fuel pump includes a negative pressure generating portion arranged to generate negative pressure when the high-pressure fuel pump draws fuel, the negative pressure generating portion being positioned lower than the fuel level “P” in the vapor separator tank.
