  • Patent number: 4653762
    Abstract: A motorcycle is provided with first and a second fuel tanks. These tanks are provided with fuel charging ports respectively. Both the fuel tanks are intercommunicated through a communicating pipe. Since the communicating pipe can be shut by a cock, fuel can be charged into both the tanks promptly through both the fuel charging ports. The communicating pipe is provided with a fuel pump actuated by a diaphragm communicated with an intake manifold of an engine. Accordingly, even if one of the fuel tanks is disposed at a location lower than the carburetor, fuel within the fuel tank can be fed to the carburetor via the other fuel tank.
