Where is my vacuum going?!

Try replacing the vacuum check valve at the booster line to booster connection.

HMMM...the check valve maintains the vacuum on the diaphram under accelleration when there is no manifold vacuum.
Even if bad, it would not cause a vacuum leak. That would have to be the diaphram in the booster itself.

Unfortunately I did not get a chance to get to my dad's place this weekend to take another crack at it... Hoping to get down there either Friday or Saturday this coming weekend.
