Re: SRT6 P0455 Evap System Leak Detected Large Leak
Not sure about your code but the smell may be this:
There is a seal on the fuel level sensor in the top of the gas tank
If you put more gas in after the pump shuts off you will be overfilling the gas tank and the gas can leak out of the seal allowing gas to run on the top and sides of the gas tank
The gas tank is located in the bulkhead wall right behind your seats
