Abstract
A device includes a housing fixed to an upper wall of a fuel tank, and having a communication opening in communication with a canister, a float valve received within the housing and floating on a fuel, and the float valve moving upward and downward so as to close and open the communication opening, and a tubular member communicating with the housing, and extending downwardly from the housing into the interior of the fuel tank. The device has through holes of a small diameter which are disposed near an upper wall of the fuel tank, and when the liquid level of the fuel in the fuel tank reaches the lower end opening of the tubular member, a pressure within the fuel tank increases, whereby the filling-up of the fuel tank is detected. When the liquid level of the fuel abnormally rises, the float valve closes the communication opening.
