    Abstract: The present invention proposes a tank, in particular a vehicle fuel tank, having a component (20) mounted therein. Such a tank comprises a tank wall (12) and a shaft (14) having a first end (18) and a second end (21). A base portion (16) is arranged on the first end (18) of the shaft (14), the base portion (16) comprising a weld area (22) on its surface facing the tank wall (12) and weld material (24) is arranged in the weld area (22) for welding the shaft (14) to the tank wall (12).
