Are you sure it's the PS pump that leaks and not the reservoir? Usually it's the reservoir's o-ring and connecting hoses that cause the leaks. If you want a quick picture/diagram of the PS pump or reservoir search any MB part suppliers catalog.

There is only one o-ring seal that has to be changed, which is #110 in the diagram. The part number is 000 466 18 80. You should also get a new c-clip part #003 994 54 45.

The most important part of the repair is the bleeding. After filling with P/S fluid, DO NOT START THE ENGINE but raise the two front wheels off the ground and follow the instruction in the pdf.
