1963 to 1973 Short MFI Electrical Fuel Pump Lower Section Resealing Instructions - On Demand Video

Be sure your Mercedes has the "short" style fuel pump. Not all models in those years had one (see description)

This is a common occurrence as these gas engines with Bosch C.I.S. fuel injection age. Most of them are now at least 20 + years old. The problem goes something like this. You start the engine cold and it will hardly run. It runs rough and idles very low and will even quit a few times.
