Craig, what kinda plastic is that line made of? I'd like to put a tee in the line so I can permanently install a vacuum gauge to monitor vacuum pump health. The gauge could mount on the inner fender, I don't need to see it while driving. If the wall thickness of the plastic line would allow it, I could even drill/tap in a fitting but I don't want to break it and have to buy a new one for fifty bucks (as you know).
