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)

MFI (mechanical fuel injection) fuel pumps are notorious for leaking fuel. Leaks are almost always due to age hardened and deformed o-rings inside the pump. Taking the pump off the car, taking it apart, cleaning it and installing new seals will almost always solve the fuel leak problems.
