A transfer device for filling the fuel tank of a vehicle using a vacuum source such as the intake manifold of an internal combustion engine as the driving force. The transfer device forces the fuel into the fuel tank until the tank is full, at which time a buoyant member connected to a pivot arm actuates a valve to close off the vacuum line. The valve and buoyant member are in separate chambers of the transfer device so that fuel never contacts the valve. The pivot arm arrangement for actuating the valve assures dependable operation since both the valve and pivot pin are free from contamination by fuel sediments.
