I believe the brake booster is at the far right corner as you look onto the engine from the front of the car.

This vacuum system I am refering to is almost to the center left side, with a blue and black check valve connected to a "Y" piece. One end of "Y" piece connects to a bi-disc-like object attached to the metal piece shilding the fuel rail. the other end, to another vacuum line that meets another "Y" piece.

Any ideas?
