Study the vacuum lines in the photos I posted of a complete intake plenum assembly.

The one vacuum line you see hanging out disconnected on the backside connects to the vacuum canister that is mounted onto the OE airbox.

On your photos, I believe #1 and #2 are the same line. It goes from the center section on the plenum to the fuel pressure regulator.

 

Note that my car is a 1990, which may differ a little....

If I'm not mistaken, Line #1 Connects to the left side (drivers side) of the throttle body, just above that one breather hose.




And another view here with intake off and breather disconnected

 

Thanks Vandit, but my # 1 seems to be coming from the front of the car ( like coming in to the engine compartment, I will stick up a photo later today ok

 

Thanks Robert.. I need to study these, Jon

 

Hi Lads,
Pls see the attached 3 pics A,B & C ..
C is the area this pipe is coming from (into the engine bay) and I took it that it is the pipe(in my 1st Pic #1) that should goto 24 Vacuum valve and 17 pressure regulator

 

Does your car have the headlight height adjustment **** on the dash? Perhaps that line that goes to the front is related to the actuators to move the headlights. US market cars don't have that feature.
