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.

Abstract: An engine working machine that has an electronically controlled fuel injection system and a fuel tank disposed in an upper portion. The capacity of the fuel tank is effectively used and a complex structure is prevented while reducing the length of the fuel piping. An engine is disposed in a lower portion, and a fuel tank is disposed above the engine. A fuel pump is mounted on a bottom outside surface of the fuel tank, and disposed projecting on a side portion of the crankcase. An extended box is provided on a bottom surface of the fuel tank, and the fuel pump is mounted with a filter and a fuel intake port located inside the extended box. The fuel pump is housed in a pump case that is fixed to a bottom surface of the extended box.
