From your bottom photo of the control pressure regulator, I cannot see clearly the vacuum hose that should be attached--it would be on a nipple at the base of the regulator, on the far left end (under the black hose and red wire in the photo). If there is no nipple there, it's possible you don't have the proper regulator. It's not unusual for the regulator to have been replaced, but if my memory is correct yours should have the vacuum connection. See if you can get the Bosch number off the top and post it here for a definitive answer.
