Default Po455 evap leak help

its not the gas cap. already replaced and cleared the code. STill get check gas cap. all the lines are checked to the charcoal canistor but don't see a problem. When the car sits there is a slight fuel smell. No visible leaks so i'm sure it just vapor from somewhere. Anybody run into this?

Gas cap won't set a p0455 unless it's misssing. Do not pressurize your evap system, your looking for trouble. You need a smoke machine. Find a shop that has one, and the leak will be found in minutes.
