Here is what I recommend. Take the vehicle to a shop and have them "fog" the system. What they will do is inject fog throughout the EVAP system at a very low pressure. Where ever the leak is, the fog will come out and they will be able to locate it.
If you try to look for the leak, chances are you won't find it. They can really be a pain.
Let me know if you have other questions.
