If you have been over every inch of the car, and can find no evidence anywhere of a fuel leak anywhere, (usually there will be staining evident somewhere if fuel is leaking), then it's quite possible that the carbon cannister is saturated with fuel.
The carbon cannister is designed to store fuel vapours from the tank, but if it gets a gutfull of fuel it becomes saturated and smells. (Is usually worse on hotter days).
This usually happens when the fuel tank is overfilled. If you are in the habit of filling it to the brim,....don't! Fill it to the first click of the gun, round it off to the nearest dollar if you must, but don't fill past that point.
If that is the cause of the smell it may take some time to disappear completely, but it will happen.
