Abstract A fuel control valve is located in a fuel tank and comprising an outlet, a liquid inlet and a vapor inlet. The valve permits to flow fuel vapor only from the inlets to the outlet and prevents drops of fuel liquid from flowing to the outlet. A float is located in the valve and prevents the drops of the fuel from flowing between the liquid inlet and the outlet. A wrapper is opposed to the vapor inlet and prevents the drops of the fuel from flowing between the vapor inlet and the outlet.
