HELP: Where does this go to????
 

Hello everyone,
I found this tube, likes like a vacuum tube, disconnected on the wife's car: '90 190E 2.6
i don't see where it goes to. Can someone please help? This is on the passenger side of the engine compartment.
Thanx..

missing more than that, egr and air pump controls there.



missing "delay" valves as well.

I've got the other hoses connected. I just don't know where that one goes to in the picture with the arrow. A pic of the other end, or something would be helpful.

Can someone please check on their 190 2.6 where this vacuum line goes. I would appreciate it very much.

Thanx..

The vacuum line you marked in the picture goes to your air injection pump, which is a belt driven unit just above the alternator at the passenger/front of your engine. As the other post said, you are missing some other items from the picture as well. There should be a "Y" tube attached to the top of each switch looking unit (as I already mentioned, the one on the right is for your air injection pump vacuum line and the one on the left is for a vacuum line going to your egr valve). The "Y" tube coming out of the top of each unit connects both systems into a single vacuum line which should run the length of your rocker cover with the spark plug wires and then over to your intake manifold. Hope this helps. I also have a 1990 190e 2.6 I just rebuilt.
