One-way check valve???

What is the little cannister thing that goes between the booster & the vaccum source called?

What purpose does it serve?

Do I need to put one on since it was removed by the PO?

Front disc, rear drum.

Weather is improving & will be test driving the ol' Camaro in a couple days!!

Thanks for any help // tips!!......

carb motors have it too. its a filter to keep gas fumes out of the booster that can degrade the rubber bladders inside the booster. Port injection systems dont have fuel running in the manifold for any real period of time, so they dont need them like the carb/tbi systems do
