Try replacing or removing the filter paper on the bottom of the carbon cannister, This cannister absorbs gas fumes from the engine when it is shut off (Evaporative Emissions Control System), it can get overloaded and cause a gas smell, if it is comming from the cannister you will smell it when you pull it out. The cannister is black plastic about the size of a coffee can with hoses going to it.
