Abstract: PURPOSE:To have stable supply of fuel to a carburettor by forming a regulator tank and a main tank as in a single piece, supplying fuel to this regulator tank via pump, and thereby simplifying the piping. CONSTITUTION:When the engine is in operation, a fuel pump 3 is driven to allow the fuel in a main tank 2 to flow in a regulator tank 1 through a fuel outlet 7, fuel pump 3, pipe 4 and refueling hole 8.
