I have had to have my red boost hose connected 3 different times in 30k miles over the past year. Thinking that may have been my issue in the past.

On further study, the new pressure converters do not hold vacuum either. the only way to test them would be while the car is running and that would be very tricky as well.
I found that the vacuum reservoir has a very small leak. The reservoir connects to the pressure converters and affects overall vacuum in the system. so they converters might or might not be faulty.
I will report back once I remove the reservoir to see where it cracked.
Edit:
the pressure converters turned out to be fine. Vacuum reservoir has a leak, not noticeable on visual inspection.
