When I fill my gas tank completely full, I get a VERY strong gas odor inside the cabin of the car. Just recently, I've been noticing that I can now smell it outside of the car, too. I've also noticed that after filling the tank full, there will be a large puddle of fuel left under the gas tank of the car. Once I use around 1-2 gallons of gas, the leak stops, and I no longer smell gas inside of the car. Ideas?
Like I said, it only leaks when the tank is full. Any other time, gas isn't leaking at all, and no odor is smelled. It seems to me if the gas tank was leaking, shouldn't I be getting a check engine light because of a de-pressurization of the tank? I'm not getting any codes at all.
