How brave are you? I sacrificed by stock hose making in a donor in building a new hose. I took my original hose and the YJ hose to CarQuest auto parts and had them merge the two into one. It ended up a bit long, but it works! PSC does supply fittings that you can use to build a your own high pressure line.

In order to protect the return line, I cut sections of the 5/8" hydraulic line that came with the pump and made short sleeves that slipped on over the hose. I had to call a few auto parts stores to find more 5/8" hydraulic line to plumb from the pump to the reservoir. I used a couple of zip ties to hold the sleeves in place.
