If I block the OUT port and apply vacuum on the VAC one, I get a "leaking" symptom,I won't be able to build a constant vacuum! Even with the new ones!!! So may be they weren't bad after all!

Anyways.

The important stuff is here:

Am I right by saying the Transducers (y31) translates or converts vacuum to a voltage signal fed into the EDS computer and that, according to preset conditions, the Switchover valves (Y27) then open or close by a signal received from EDS computer?

It would seem logical to me!

Let's see how the pictures show on this reply (1st test!).

Bye
