anyone using AN fittings + braided hose for vacuum lines? i was looking up on the push to connect fittings but i don't know how it would hold up on a dd. would the braided hose work better?

 

I've done it in the past, not really sure if it's cost effective.

The push-lock fittings, as long as you go with a quality brand, will not give you any headaches down the road. Some heat shielding can do wonders

 

It would be so expensive to do braided lines for vacuum, and completely overkill. But it would be baller.
