I have replaced my high pressure hydraulic hose, on the power steering, using my refurbished
hose ends. I want to test the hose off the car before I fit it. Have some original MB data sheets that suggest that the pressure should be between 55 and 65 bar (825 -975 psi) at 1000 RPM but nothing on what the re-circulating valve opens up at. Is this the pressure range that it opens up as well?
