I have read more than a few threads, but none specific to the W126 and the 560.

If I understand right, the high pressure hose comes from the pump and terminates at a metal line.... but where? I have not looked yet, honestly.

What is involved in repair it? Mine is leaking near the pump. In addition to the dang pump leaking. Both I want to take car of now that the weather is warming up. Pump I have figured out, already rebuilt it once. Its this line I dont understand.

I guess what I am looking for is the details. What line size do I need. Recommendation on line pressure rating. It seems I can reuse the fittings on the ends. But how do I remove the line, seems to snake through the engine. Could I just re-route the line to a better location can cut the old line to get it out?

Anyone who has actually done this, I could use some pointers. Photos wold be great if anyone has them!
