A ventilation and/or a pressure-equalizing system for a fuel tank, in particular for a fuel tank of a motor vehicle, includes at least one aeration and/or de-aeration line leading into the fuel tank, via which the gases and/or vapors may be removed from or conducted into the fuel tank. A collection device for liquid fuel is coupled into the aeration and/or de-aeration line, the collection device including at least two chambers, of which one is used as a temporary storage device for liquid fuel and is connected to a return line into the fuel tank.

Ventilation and/or pressure-equalizing system for a fuel tank

The invention relates to a method for filling a fuel tank (,) with a filling conduit (,). The fuel flow entering the tank is directed by a through flow sensor (,) in order to control and monitor the filling process. A particularly suitable tank system (,) for implementation of said method comprises a fuel tank (,), a filling tube (,) surrounding a filling conduit (,) and discharging into said fuel tank, an adsorption filler (,) connected to the gas area (,) of the tank (,) and a through-flow sensor (,) which detects the flow of fuel in the filling tube (,).
