I had a rip in the T-fitting that connected to the lower intake vacuum line and had a buddy patch it up with RTV gasket maker and a piece of silicon. Well after doing the ZZP coupler install my vacuum no longer toughes -10 or below like I used to after the fix. I bought a few fittings from Autozone but they are super tight, but should work fine. What I'm asking is, is there anyone who knows the original part numbers on these fittings going around the entire vacuum line that runs around the SC?
