View Full Version : LY6 vacuum ports

Hey guys,
Looking for where the vacuum ports on an LY6 go? There's one on a sensor that clips to the drivers side fuel rail, I have no idea what that is or where the other end of the vacuum port goes.
And on the passenger side, there's one right behind where the fuel rail loops over that has a little nipple on it.

any help would be greatly appreciated.
