I’m working on the vacuum hoses and have a few questions.

1. **Cold Start Valve:** I believe the larger port connects to the Auxiliary Air Regulator (AAR). Where does the smaller port connect?

2. I’m missing the EGR valve, all of the metal vacuum lines, and the deceleration valve. Does that matter? Can I start the engine without them?

3. What is the middle port on the fuel rail for? Where should it be connected?
