can you be a little more specific as to where it is? Is it by the brake booster on the driver's side by the firewall? I see a few green and black valve's/"T"s by the firewall.....thanks!!
It is directly under your intake between the head and battery. It is normally connected with all the other factory solenoids and vacuum lines. You will see the two green ports. One pointing towards the front of the car and the other pointing up towards the hood. It has nothing to do with the brake booster. I believe it is an emissions related thing that runs all the way back to the charcoal canister. Simple remove the check valve and run 12"-18" of 3/8 vacuum line from the nipple on your intake to where the check valve port was. It sounds confusing but takes 5 minutes if you know what your doing. Be sure to use zip ties always.

Ok i am running the gt40 turbo and do not have an intake on it just a screen... do to room issues... How would i go about fixing this without an intake on my car... could i just vent it to the atmosphere?
