I believe it's a one-way valve to prevent vacuum loss inside the booster. It stops the vacuum from bleeding out and back into the engine during low vacuum moments.

Re: Canister off of brake booster
Is the check valve incorporated in the elbow, then?

The check valve is the plastic piece the hose attaches to on the front of the brake booster. This is just a filter and was not used on all years and all models.

Re: Canister off of brake booster
One more thing I have to ask is can the canister be hooked connected to the intake manifold or does it have to be on the carb

It can be connected to ANY full-time manifold vacuum source.
That filter is to help protect the large power brake vacuum diaphragm from gasoline fumes attacking it and shortening its life.
The one-way valve is in the elbow connector at the brake booster.
