The EVAP circuit might have a leak or there is a fuel leak at a line. It is hard to find fuel leaks as they evaporate so fast. Although if you smell it in car I would check the EVAP, the circuit should be on a sticker under the hood of your car. Also look and smell very carefully under the hodd in the engine bat right after using your car to tyr and see if you can't find the leak.
