You would need to go to one of those Mercedes parts sites that has pics of the Fuel Injection Pumps and shows the results by the Mercedes part number that is on the small metal plate on the Fuel Injection Pump. That would get you the Mercedes part number for that item.

There is also a Bosch number for the Fuel Injection pump on that same plate but I know of no way other then going to a certified Bosch Fuel injection shop to get the part number and of course the bosch number will be different then the Mercedes part number.

What else have you done to troubleshoot the shaking? I ask that because the delivery valves are usually the last issue that people deal with when trouble shooting the shaking issue.
