I will admit, I messed up. I received my FAST102 and installed it using a guide online. The small vacuum port on the rear of the manifold was broken off fairly flush with the manifold and the install guide I used for a corvette stated to put a screw and RTV in that port. I realized last week that I could not select my HVAC vent positions and traced it to the one vacuum line that should be connected to the rear of the manifold. I am now trying to determine my options for fixing this. I either have to remove the manifold (fuel rails, etc: lots of work), adapt some sort of barbed fitting to the spot and attach there, or tap into a different location/vacuum line. I am slowly becoming more familiar with the vacuum system as I have been tracking this, but I am not sure where would be a good line to tap into. I would like to avoid running a line from the firewall all the way to the front of the manifold.

Please let me know thoughts and if anyone else has run into something similar.

Shouldnt take you more than 15 min to pull the intake off. Then just get a brass fitting. The small nipple on mine broke too and I put a brass fitting in there n its perfect.
