I am in the process of having three high-pressure power steering hoses custom made (reproduced) by a hydraulic shop here in Maryland for my E63 AMG. The “superseded” factory hose from MB fits and works, but is not as good as the original hose, so I’m having repros made.
The spares will go to a shop owner friend for eventual use on customer cars.
It is what it is.
I had a high pressure fuel line made for my G-wagen about 5 years ago as that hose was NLA from MB. It’s been fine ever since.
