928Belgium

When I bought my 928 there where 2 vacuum lines connected questionable.

There was a line going from the diverter valve in the air pump line (photo1) to what I think is de deceleration valve (photo2).

Looking at some post on this forum gave me a clue that this diagram from photo2 should be connected to the middle nipple at the back of the throttle body (photo3, at the moment this line is blanked off), right? Can someone confirm this?

And can somebody tell me where the line from photo1 should be connected to?

Thanks in advance!

The Diverter and the Decel valve connect together via a T piece which in turn connects as you say to the middle nipple on the throttle body.
