Reliable vacuum line for wg
 

I am torn as to what to do. When I took the car apart the napa vacuum line broke and was very brittle due to the heat it was exposed to (partly because I routed it with no regard to the 1500ish degree turbo vicinity which won't be repeated). I would like to avoid this so the routes I am considering are:

Input? Have a better solution? Thaaaaaaaanks!

I have NAPA carburator fuel line under there for signal.

How many [track] hours do you think you have on those lines?
