A fuel tank for a motor vehicle is described and has a collector tank disposed in its interior for extracting air from it. The collector tank is connected to a pressure-equalizing device that is disposed outside the fuel tank and has an activated carbon filter. Fuel penetrating into the collector tank is extracted by suction by a pump configured as a suction jet pump. As a result, the fuel tank has particularly low levels of fuel emission.

Fuel tank

The invention relates to a ventilation device for fuel tanks, wherein the ventilation device comprises a compensator reservoir arranged in the interior of the fuel tank and at least two ventilation lines. The ventilation lines run from below the upper tank wall to the compensator reservoir and extend in the latter toward an opposite tank wall. The apparatus according to the invention is particularly well suited under all static and dynamic stresses for ventilating fuel tanks.
