ABSTRACT:
A reserve tank is built into the vehicle, and communicates with a filler pipe. A sleeve extends into the reserve tank, the upper end of which defines the reserve capacity, and the other end of which is connected with the inlet of the fuel tank. The contents of the reserve tank can be transferred readily into the fuel tank via a bypass with a valve. An expansion tank with a volume of at least 10% of the tank volume, is likewise connected with the fuel tank via a pipe. An air vent connection of the fuel tank and an air vent connection of the expansion tank are alternately connected with the atmosphere via valves controlled by a closure device, in such a way that, when the filler is open, the air vent connection of the fuel tank is opened, while the air vent connection for the expansion tank is shut. A non-return valve is incorporated in the passage which leads from the connection on the fuel tank via the expansion tank into the air vent connection for the expansion tank.
