the vacuum accumulator seems to loose vacuum at the rate of .5 inHG per minute. might just be the connection tubes not providing a proper seal. unfortunately I cannot fit a screw clamp due to being such a tight space. I doubt it would affect the overall system performance.
a visual inspection shows no cracks.
turned out both pressure converters where not holding vacuum and so ordered some new ones from eBay. They made a small fan noise when vacuum was applied.
Someone said they can be reconditioned but they seem to keep failing and at 40 dollar price point probably not worth messing with it.
Thanks for all the help!
