Yesterday I took my hose to a place called "Hose Power" and they rebuilt it right then, on my lunch break. This was the hose from expansion valve that connects to the hard line that passes the valve cover. This was the only hose the parts houses didn't have. Stealership wanted $177 but the hose shop was able to re-use my end peices and replace the hose with quality Good-Year hose. Cost was $45 and it took about 30 minutes.

You could ask hydraulic shops if they'll do it for you if there are no "hose-only" shops around.

Good luck and I've got pics of the before and after if you'd like to see them.
