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. The first and the second fuel tanks may be combined to constitute a single fuel tank.
