With my 300 Adenauer 4 pieces of the things are installed in the petrol lines, also for the return. Some time ago I broke one during the assembly. So I have one less in the system. I believe that the engine since then consumes about 186l/km. The damper tanks are made of zinc injection molding, so can not be soldered so easily, and whether soft soldering makes sense I don’t believe. At a company in Mannheim costs an almost one five hundred EUR !!!!!! Inside is only a diaphragm under spring pressure, that I believed there is the air pressure in the mountains regulated. So if I leave one away, before or behind the injection pump ? Does anyone know ? Or is the consumption result of a leak in the tank ?? Hi Hi….( Picture no. 45 )
