Smell of gasoline by throwing back.

Hello, I have a Citroen ZX and when you throw back it smells like gasoline inside the car. What can it be due? Thank you.

The most likely friend is that you have the broken O'Ring of the fuel pump cover that goes on the pond under the rear asieth of your vehicle checks if your seat is wet or the other one that can happen is that you have the broken exhaust in some place that causes that smell inside your vehicle when you end up back I hope my answer serves you my answer luck

I recommend that you revive the clamps from the fuel filling duct until the arrival at the engine is very lucky

Thank you very much for the speed answer.
