Hey all, this is going to be a lot, and there will be some pictures involved from other sites. This is a bunch of questions I thought about while blocking off and installing a lower intake manifold on my S4 TII engine. Any other forums or posts are greatly appreciated.

• First off, what are these vacuum nipples for?

If my understanding is correct, nipple 1 is for the fuel pressure regulator. Now I am switching to a parallel system according to FC3S pro. (FC3S Pro v2.0:Â Mods - Fuel System) They have this picture which has the FPR attached to a vacuum hose, would it be this one?



The second nipple I am not sure what it is for, the line was long, and is now cracked. Please let me know where this is for.

• Now to block off plates, I currently installed the EGR, ACV, and Sub Zero block off plates. I will not be installing the BAC valve block off. I am confused where the split air block off goes. If anyone can shed some light that would be nice.
• There are 3 nipples on each side of the UIM, is there a diagram what connects to these, or can I block most of them off?
• Some forums talk about a restrictor pill in the pressure sensor by the passenger headlight, what is this? Do I have to put something in there?
• Lastly (I think), Ive seen some conflicting things on where the PCV is. I want to install a vented catch can. Where is the right place to connect?

If there is any other info that needs to be added, let me know.

1. that is the FPR line
2. is an injector air bleed, it should get hooked up, i think it goes to one of the nipples on the intake.
