c20xe vacuum diagram
« on: March 30, 2018, 22:08:16 PM »
Anybody who has this? I've went through the Haynes manual a couple of times, searched Google, searched here, no luck...

I have 5 blocked-off vacuum lines I want to put back where they belong, 1 on the left side of the throttle body (when standing in front of the engine) and 4 coming from the inlet manifold. I'm guessing the one on the TB is supposed to go to the carbon canister, and maybe best to stay blocked?

On the throttle body, there are 2 vacuum lines one right next to the other. When looking from the front of the car, the left one is for the fuel tank vent valve (and then to) carbon canister, and the right one is for the fuel pressure regulator.
Then below these 2 vacuums, there's another one for the cam cover breather. There's a coolant line running right through it.

Thanks for your reply!

I only have one blanked-off vacuum line on the TB itself, got that one figured out. But what are the 4 on the intake?

There's 3 on this pic, and one more on the other side of the TB, also coming from the intake.
