FWIW my local Parker store has a machine where they can cut off a steel line and weld/solder on their proprietary barb or whatever it is and then crimp on the hose. Machine does it all in a minute or two. Adds $7 to the cost of the hose being made. As Bill says we have also had stub adapters made where the rover hardine is cut off just above the steering box and 8n male fitting welded on and then female 8n hose to the pump for the high pressure side. This is what we do with the Cummins install. AN fittings are the industrial standard in this country and make it so if you ever have a hydraulic issue in the future, pretty much any hose store to include most NAPA locations can make you a new one in a few mins for short $.
