ABSTRACT:
A fuel tank is provided with an atmospheric air introduction hole so that the fuel tank communicates with the outside. As a result, the interior of the fuel tank is maintained at a pressure level between substantially atmospheric air pressure and positive pressure. A canister may be connected to the atmospheric air introduction hole. When an internal combustion engine starts up, the fuel tank communicates with an intake path. Internal combustion engine startup places the intake path under negative pressure. Under negative pressure, fuel vapor is supplied to the intake path from the fuel tank whose pressure level is between substantially atmospheric air pressure and positive pressure.
