I have never had to bother with this line. I would imagine it is just regular plumbing. Hopefully you can just tear it down and just cut the same size new hose down to fit. Sadly, "tear down" seems the likely scenario here. Plan for at least 1/2 a day. In any case, make the best of it and replace any other lines, gaskets, and maybe even the S/C oil while you are at it. Knock as many birds down with that stone as possible. Good luck.
