Greetings,
Having a vacuum diagram hell.
I pulled off the the warmup enrichment compensator (warm up regulator) off my 1981 mercedes 380sl to do some other work.
In the mean time I also worked on the vacuum lines. My problem is that there is three vaccum ports on this compensator, my vaccum diagram shows only two on both of the sides, there is one port on top and I don't know where that one goes to.
Please help.

Dmitri
