Abstract: A safety arrangement for a DME fuel tank of a vehicle, adapted to release an excessive pressure from the fuel tank, including a spring-loaded pressure release valve adapted to open at a predefined pressure level, where the safety arrangement further includes a housing mounted on the fuel tank and having an outer opening closed by a lid, where the pressure release valve is arranged in the housing and where the housing is provided with an outlet pipe having an outlet opening, and where the lid is adapted to melt at a predefined temperature, thereby allowing gas to exit the pressure release valve through the outer opening of the housing when the pressure release valve is open and the lid has melted. A small gas leakage caused by an excessive pressure can be discharged downwards through the outlet pipe and outlet opening towards the ground, and a large gas leakage, caused by e.g. a fire, can be discharged outwards from the fuel tank, away from the fire.

Abstract: In a reservoir for running material, for example a fuel tank for a motor vehicle, a tank fitting is mounted in the tank, for example a fuel level meter. The upper end of the fitting is rigidly attached to the top wall of the tank, while its lower end is guided by guide elements, that allow limited movement of the lower end in a lateral direction. The guide elements are created of a cylindrical extension of a bottom plug that is screwed into a drainage opening in the tank and an element attached to the lower end of the tank fitting that has an opening, into which the cylindrical extension is inserted.
