Hey guys, just wanted to let you all know I replaced all the vacuum lines and the total cost using OEM BMW hoses wasn't too bad ~ $150. Its a little high for hoses but I wanted to stick with OEM and the colors designate location. Overall the vacuum job wasn't bad at all and I won't have to worry about possibly getting a vacuum leak for another 50-70k. I'd highly recommend tackling this job if you are handy as preventative maintenance.

Here are a couple pics showing the all new lines installed:
