There's a LOT of hose on a Box, so you will need a smoke machine (easy to make) to get a full test. Duramertic would be helpful if you had one.
The booster was hard to test because it takes a bit of vacuum to pull it down to check. A vacuum pump is helpful. We could hear ours leaking with my head under the dash when that car was idling.
