Vacuum pressure reading

Suspecting a vacuum leak in my 993.

Can someone tell me what is the vacuum reading from the plugged port in the middle and top of manifold? It has identical pressure from the small port below. The small port goes to fuel pressure regulator.

I left the same message in Rennlist.

Thanks.
