Bendix master vac power brake set up

Early As used an inline check valve- I can't find a picture right now, but it was kind of similar to what you've shown. Looks like it was a leaker and the PO taped it up because he couldn't find a replacement?
I think @65dartcharger may be of some assistance here.
Thanks. I actually broke it, it was very fragile from years of sitting. I super glued it back together then used the duct tape as some added insurance. If this item item is correct for the car I would love to find another one. It didn't appear to be a valve, it seemed like its would block all vacuum from the intake, but I'm sure I'm wrong.
