This is how I did mine. Just ran Russel Braided line down the upper link and T'd to each side. If you can find a local hose place usually they can make them for much cheaper than you can get them through Summit/Speedway/Jegs.
It's off a Kubota is the best I could find, no displacement numbers though.
