Got some nice push-to-connect tube fittings and nylon tubbing from McMaster-Carr so I can do all my vacuum lines and not have to worry about anything coming loose. I ended up getting 25' of tubing and about 12 assorted fittings for about $50 or so way cheaper that doing it with SS lines and AN fittings.
They come with teflon tape already applied on them : )
Here is an example of how they will be used
I am planning on using this for all of my vacuum/pressure lines which should make it one very nice and clean install. Tubing is rated for 200deg F. Fittings are rated for 250-299psi. This makes it more than capable of handling my underhood temperature and my desired boost pressure of 40 psi max.
