Abstract
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.
