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.
