hey everyone,
pulling apart the top end of the 2.8 today to clean the TB, replace coolant temp sensor, and clean IAC valve.
when i was ready to take off the throttle body i noticed there was a vaccum line on the top right side that wasn't connected to anything...moreover, it had so much crap on it there is no way it has been connected for a long time.
i can't figure out where this vaccum line should go! any help or diagrams would be appreciated.

if looking down at the top off the throttle body (while its still on the car) the vaccum line is sticking out at a 45 degree angle from the right side.

thanks!

Hope this helps or at least you can call it out .

 

see if this works..

 

that last diagram would probably help but at 100% size it is still to small to read!

does anyone have pics of the throttle body or any time to go look real fast?

 

sorry... the forum software shrunk it...

pm me your e-mail and I'll shoot it to ya. It does show one comming off to the right going to a tee that says 'A/C and/or Quattro', then it continues to the 'EVAP Leak Detection Pump.'
