Vacuum Line Question

**jfl330** · 06-20-2011, 07:44 AM

I am putting my intake back on after replacing the knock sensors. Besides the AIR system, what else connects to that port? I would like to just cap it off on the back of the manifold now as it is easy to get to.

Air Vacuum Hose *, Break booster and HVAC

The HVAC is the hard small plastic line and it connects to the bottom port.

You need all of it and will need to connect it all back. unless you don't want breaks or AC?

* - this is what alldatadiy is calling it.

that covers it well. no ac sucks. brakes just slow you down anyway

Well I guess I have to provide for the HVAC line, this is Florida, it's 10,000 degrees out!

But I will kill the AIR System line now instead of going back in later.

Thanks!

Good man. The AIR system just clutters the engine bay anyway.

So I understand this straight....

The 01'-02' has no egr, but still has the air pump system?

If you eliminate the AIR just remove the T on the back of the intake and just connect the small line for the HVAC. Is the small tubing going to the passenger side firewall area.

From the factory they have the AIR pump and all the tubing that goes with it.

Cam change in the 01' & 02' allowed the egr to be eliminated.

Correct.
Always best to remove dead weight anyway.

hey, quick question, if the vaccum tube that connects to the MAP is damaged (cracked by an idiot installing an LS6 manifold...) will this cause weird running conditions like surgin idling and stumbling when punched at WOT?
