I am getting ready to repair leaks on the power steering, hydraulic suspension system on 1992 500E. I would like to rebuild the reservoir and pump and I would like to replace as many of the hoses as possible. I know the low pressure hose between the reservoir and the pump is definite. Here are my questions: What other hoses should be done? It looks like there is a pressure hose from the pump to the right side of the car that is likely a source of leaks. Does anyone have a list of part numbers for the seals on the pump, reservoir and the high pressure lines on the system? Also, in looking at the how to tutorials, I saw one on rebuilding the reservoir, but are there any on the forum for rebuilding the pump? Last, would it make more sense to buy a rebuilt pump or to follow my plan to rebuild it myself. Thanks for any information and recommendations.
