NOTE: rear shaft seal is not covered in this video – this information can be found online. If you have a deep groove worn into the shaft from this seal, you may have to install the new one in a slightly different position to contact an undamaged part of the shaft to prevent leakage from the backside of the pump.

The MB re-seal kit only includes the front cover o-ring and rear shaft seal – if your pump continues to leak from the front cover after replacement of this while operating, the internal O-rings will be leaking. With time and heat they have all gone hard and brittle now anyway.The internal o-rings have to be sourced from the aftermarket. They are not available as a spare part from MB. They want the whole pump replaced in such case.

Also note, i suggest using something like silcon o-ring grease to allow easy installation of the internal o-rings. Oil on its own may allow the rings to bind and be cut, chipped or shaved, resulting in enormous leaks.
