Yes, it could be anything with the EVAP. If you suspect the EVAP system has a leak, take the car to a shop and have them fog the system. What they do is force fog throughout the EVAP system. If there is a leak, you will see the fog leak from that spot.
Again, if you think it may be the EVAP system, pay the few bucks to have it fogged. Otherwise, you will go crazy trying to find the leak.
Let me know if this helps. Also, is the smell back?
