Vacuum Control Plumbing

- locate black pipe that runs front/back along upper driver’s side of intake

manifold. Remove single 10mm bolt (A) holding bracket at front-center of intake

manifold (note: rear bracket should already be loose when driver’s harness

cover was removed).

- follow black pipe rearward - it connects to a rubber hose, which in turn runs

into a ‘T’ connector (B). The hose that runs from this ‘T’ over to the rear of the

intake manifold must be disconnected at the manifold (C). This is a large press-

fit ‘L’ connector which runs into a rubber grommet in the rear face of the

manifold. Carefully work the ‘L’ fitting loose from the grommet, twisting and

pulling it rearward from the manifold.

- Return to the black pipe where it connects to a rubber hose - cut and remove

the factory crimp connector (D) (don’t damage the hose) and disconnect the

black vacuum pipe from the hose. At this point the intake manifold vacuum

plumbing is disconnected from the car. During reassembly you will replace this

crimp connector with a screw-type hose clamp. Allow the black pipe to rest on

the intake manifold.
