It was simple, took about an hour since I wanted to do it perfectly and only once. Only one observation....to attach hose #1, the instructions said I might need to adjust the roof hose fitting. It was hard to turn the fitting at all to move it out of the way. I used a ball peen hammer to tap the fitting over to make room since it would not budge with a wrench.
Just seemed odd to be hitting the fitting to move it. I usually save the hammer for working on the tractor!

Alfred...Good luck with your work...you should be fine. This was one of the first things I did when I acquired my 03 XKR last April. Enjoy!!
