Abstract
A fuel tank for a vehicle includes a main tank comprising a first tank volume defined by an outside wall and an auxiliary tank extending from an aperture provided in the outside wall. The auxiliary tank is formed as a pocket-shaped continuation of the outside wall into the first tank volume bounded by the outside wall. The auxiliary tank forms a second tank volume which is separated from the first tank volume and opens into a filler neck which runs inside the first tank volume and emerges on the outside wall of the main tank.

A fuel tank for a vehicle, comprising:
- a main tank comprising a first tank volume defined by an outside wall;
- an auxiliary tank extending from an aperture provided in the outside wall of the main tank, wherein the aperture is closed by a tank cap along a fixing area formed on the outside wall, the auxiliary tank formed as a pocket-shaped continuation of the outside wall into the first tank volume bounded by the outside wall, wherein the auxiliary tank forms a second tank volume which is separated from the first tank volume;
- an assembly device for attaching the tank cap to the auxiliary tank, the assembly device disposed along the fixing area, wherein the assembly device lies inside the auxiliary tank;
- wherein, the auxiliary tank opens into a first filler neck which runs inside the first tank volume and emerges on the outside wall of the main tank.
