Vacuum Testing --- Need lots of help w/3 vac hoses (??)

Hello,
I am testing my car for vacuum leaks and I found some and I have no freaking clue which ones should leak, shouldn't, blah blah. I have 3 hoses in particular that I'm wondering about....
1. I tested the charcoal canister - the line from the intake manifold to the canister, it leaks (holds no vacuum), the check valve/diaphragm allows air to be pulled through it. Is this correct?
2. I also tested the line coming from the gas tank to the charcoal canister - it leaks (holds no vacuum) - is this correct?
3. I tested the line that runs under the windsheild to the vacuum canister, it will hold vacuum, but it takes alot of pumps with the mighty-vac, and doesn't hold the pressure the whole time. Is this correct?
Inspected the canister for cracks/leaks, there are none. Could it possibly be the valve on top of the vacuum canister?
Thank you for your time!
