I am having a bit of trouble finding where this vacuum hose is supposed to go (My car is a S4 N/A). On the front of the Dynamic Chamber there are three vacuum nipples. I know that the large one goes to the oil lines, and that the bottom one goes to the vac rac, but where the hell does the middle one go (its the middle one when looking at the FSM). The FSM pic has it going by the Sub-zero start thing, but the LIM is blocking it in teh drawing, is it for the Sub-zero start? Does anyone know, cuz I have to put the car back together by tomorrow before I go to work so that my dad will help me tow start it.

 

That one goes to a nipple that is located b/t the two oil injector nozzles on the manifold. The two oil injector nozzles that are within a few inches of each other. It's for primay fuel injector bleed air. Ii's a good idea to keep this vac hose in place.

 

So it does go to the nipple on the LIM. Alright, thanks hailers.
