The following have been added to the vacuum parts album:
This connects the deceleration valve and brake booster to the air plenum.
Placement can be seen at ratwell.com.
Connects the auxiliary air regulator to the intake elbow (S tube.)
There are two pieces to this. There is a metal tube that slides inside the rubber elbow on the side leading to the intake elbow. I have not been able to find a part number for this item.
