Abstract: A fuel supply system includes an intake flow passage communicating with an intake port of a gas engine, a fuel shut-off valve assembly for blocking a fuel supply passage to prevent supply of a gas fuel to a fuel mixer, a vacuum flow passage communicating with a vacuum actuator of the fuel shut-off valve assembly and a crank chamber of the gas engine, and means for holding the vacuum flow passage open when the gas engine starts, such that a vacuum produced in the crank chamber is used to actuate the vacuum actuator for switching the fuel shut-off valve assembly to an open position allowing supply of the gas fuel to the fuel mixer.
