Bendix master vac power brake set up

My 65 Barracuda came equipped with the Bendix power brake set up with the vacuum canister on the fender. The canister appears to be in great shape for it's age, I'm going to pull it off and make sure it's holding air then freshen it up.

The piece in the pictures if between the intake and booster. I can't imagine this is stock, even without the duct tape. This piece is closed on both ends and appears to block all vacuum from the intake to the booster.

I'm noticing the vacuum hose fitting nipple is listed in the 65 parts manual, #1944154. There is an Asterix, noting a change or addition. Most sites like fee bay say this doesn't fit my 65. Is this what I need, or is there a reason someone would have blocked intake vacuum to the booster?

Thanks everyone!
