SDL 1987 I have A vacuum Line the Comes from the little Filter near the Turbo Area that is attach to the inside of the Car but I do not Know where should be attach. Now is not conected to anything. The Other came from the Inside and goes to side of the Injection Pump under the ALDA. Does any body have a good diagram of an SDL of the Vacuums lines and Where should the hose should be connected on the inside. Thanks

That hose dos not connect to anything,its where air gets sucked into the system and was put thru into the inside of the car because the air there is likely to be cleaner than under the hood,those germans thought of everything. Don

So Both Connectors jost the connectors take ventilations from the Inside? Wow amazing. So just to double check I found the DIagrams!! 1 The Line that goes to the Filter is also conected to the vaccuum transducer, exhast gas recirculation valve that goes take air from the Inside. The question should Be How many Inches of vaccum shoul I have depending which valve Am I using? because my problem I think is that there is not enough fuel delivery when the Turbo enter in action. What I am Having is that the car accelerates well good (could be better) but lets say that it is on second and when it reachs 40MPH and 4000 RPM or 4500 RPms, It stays and does not get any more MPH and the reading on Turbo was 9 LBS. What could be the reason? I do not want to play with the ALDA but makes me sounds like I will.

I also have to add That to continue acceleration I have to take out the pedal to lets the Transmition Shift and continue with acceleration. I put a vacuum messure on the line that goes inside and give me 25" but that line as you says goes inside and does not give me any reading when is like it is!!
