If the vacuum line your are talking about goes to the brake booster, it is a check valve to protect the booster from fuel vapors and backfires. It will flow with vacuum on it but will check if it gets a pressure pulse such as a backfire and it will close when the engine is off to prevent fuel vapor from entering the brake booster and destroying the diaphram.

If you've got 1 vacuum line going in from the manifold and 2 going out, 1 to the dash and 1 to the headlights then it's the one-way check valve. Keeps pressure in the headlight system when the engine is shut off I think.
