ABSTRACT:
A fuel supply system for a boat includes a vapor separator tank connected to a fuel tank mounted on a hull of the boat to contain fuel therein, an injector to supply fuel to an engine, and a high-pressure fuel pump to supply fuel that is contained in the vapor separator tank to the injector. The high-pressure fuel pump includes a pump main portion having a fuel path and a pump driving section that are separated from the fuel path of the pump main portion. The fuel supply system minimizes deterioration in engine startability.
