My OEM power steering hose had the common leaking problem. So while I had the engine out, replacing it was a definite must! Unfortunately the OEM high pressure assembly costs almost $300! I figured that amount of money could be better spent on some performance upgrades, so I looked at my options.

A bit of Power steering fitting education:

I work in a bit of a fitting related industry (plumbing, mechanical, and gas), so I know what I am looking at when it comes to hoses pipes, and connections. I realized that the way the hoses come from the factory is with a hose ferrule crimp connection. A very standard means of making a permanent coupling of hoses to hardlines or swivel connections. Thing is, I had access to a common crimper, but not for the certain pressures we are dealing with in a power steering system - which can be up to 1500psi working pressure! I had to pull a few strings, but overall, this took nearly no effort and saved me $250.

Directions:

1) You NEED a dremel with a cutter wheel! 
2) Make an alignment mark with a sharpie on each end of the hose. mark the black hose all the way to the hardline (for a reference point)
3) Take this and carefully cut through the hose ferrule - the crimped connector that couples the black power steering hose with the hardline on each end of the hose. - This also means cutting through the black power steering rubber hose, it can get stinky. But whatever you do - do not cut through/into the two hardlines (the two banjo ends) those are the parts you re-use! It is ok if you scratch/cut them up a bit (it's inevitable). But don't intentionally do it!
4) It might take some patience, but once you get through the outer shell with whatever means possible, you need to bend the ferrule casing back to get the hose connection out. I used a sturdy screwdriver and a hammer and smashed away at it with it clamped in a vise. It takes a bit of work!
5) Once you get the ferrule off the hose, take hardline and pull it out - voila! thats what you need!
6) Repeat with the other side
7) IMPORTANT! - Keep the black hose and the two hardlines. You need to use the hose alignment marks you made earlier to match up the right angles for your new hose.
8) Find a local hydraulic shop that will repair a hydraulic hose for you (thats what you have)
9) Go there and say "I need 3/8" hydraulic hose matched to this length and crimped on, matching these alignment specs etc.) If they argue it's metric, tell them SAE 3/8" Hydraulic hose and a 3/8" ferrule for 1500psi working pressure will work.
10) Done deal, should cost you a maximum of $30



Sorry I couldn't get more pictures of the process, If I do another hose I will do an update!
