Well it didnt' take long for the frustration to start.

I checked the inj pump valve and I not sure that is it. All the pressure around the unit id 3-5inches. So it can't govern the flow if only 3-5 is there.
Below is the diagram of the vacuum system.

Maybe someone can confirm this with me, I don't think the diagram is correct? If you follow the line from the vacuum pump thru the white line and the first Y it then goes to the second Y and this goes to the transmission???? that would mean the transmission get full vacuum from the vacuum pump and it woudl not go thru the inj pump valve and the air switches on the vavle cover, Am I nuts or do you guys see it this way also.

Item's #4 are the 3 way rubber connectors.

With this diagram I don't see how the air switches or inj valve are inserted into the system. the diagram is from Performance Products, But the one in the Mercedes technical manual has the same flow.

If this is how its set up in the 240D then I should have 22 inch at the black line going to the tranny, I don't so obviously either the diagram or the car is incorrect.
