If you can't find a line, try Amazon Hose. They are a local shop here in Tampa that can make just about any kind of line or hose. I had a leaking high pressure line going to the rear steering rack on my hicas. That line from Nissan was like $400! I took it to Amazon Hose and they made a new one for only $60 you can't beat that! that line they made hasn't leaked once.

Good luck!
