The rubber tube running below the booster, blocked off with a bolt is the vacuum line from the intake manifold. I connected the vacuum tester to the nipple that is immediately below the bleeder on the front of the canister. (aluminum colored fitting in the picture).

The visible nut on the back of the hydrovac (left in the picture) is for the rear mount.
