Thread: Noob Question - Vacuum line on Eaton M90

Hey everyone,

Total noob question here but where does this vacuum line go on the Eaton M90 on my 2000 Regal GS:

PICTURE HERE - SEE THE RED ARROW

In case it's hard for anyone to see, it's the vauum line on top of the Eaton M90, not the brake booster line and not the boost bypass valve line.

I have searched unsuccessfully, some people say 1 thing, some say other, so just looking for a solid answer.

Vacuum HVAC controls inside the car.

It should run down the firewall/stut tower area and into the cabin of the car.
