What is the 2nd vaccum line on the back of the intake?
What is the 2nd vaccum line on the back of the intake? I just installed my polished Weiand last night. The whole motor is polished, I'll post pics when I can.
There is the big vaccum line that goes to the brake booster, there is another tiny one that the book says goes to a vaccum switch. What is that line going to? Does anyone know?
Thanks.

Thanks. that is correct. It comes off the back of the intake over to the passenger side where there is a vacuum Tee, one side of the Tee goes to the HVAC harness, the other side of the Tee goes to a vacuum canister under the front right frame rail.

When I get a lil extra ching I'll spring for the Zoop. I heard it doesn't work well at high temps though.

It is your HVAC vacuum controls. When I did my cam swap in January that line slipped off and I had no vents, only defrost. Ran a vacuum check on the system and saw it wasn't holding vacuum. Once I felt around and looked for a broken line I found that one unplugged. Plugged it back in and all was well. It should connect on the passenger side
