Abstract
A fuel tank for vehicles, particularly passenger cars, has a filler neck which, in the area of a connection to the fuel tank, is guided around the upper edge of an adjoining body part or chassis part and penetrates a lateral fuel tank wall, a partial area of the filler neck projecting into the fuel tank interior. So that the maximal filling level of the fuel tank can be lowered under the plane A--A of the adjoining body part or chassis part, and therefore a sufficient expansion volume is ensured, it is provided that the end of the filler neck which projects into the tank interior and a filling ventilation extend below the level A--A defined by the upper edge of the body part or the chassis part, the maximal filling level H being determinable by the highest point of the filling ventilation situated in the tank interior.
