WIS Sheets for the Fuel Rail Sensor Replacement

[Brian23]

Hi I have done an OBD with an ICarsoft and it says that the Fuel Rail sensor is faulty. I have bought a new one from MB, but now need the instructions of how to dismantle the engine parts to get to it. This IS NOT the fuel sensor that is on the fuel tank, see photo. It would be much appreciated if someone could let me have the service sheets for this.

Or if you have a link to a you tube vid on this.

Or even if you can point me in the right direction as I have spent hours searching the net, but can't find anything that show what to take off the complete engine.
