I believe the charcoal canister is responsible for dealing with gas vapors Check your EVAP vent valve. It controls fresh airflow into the EVAP canister. It may be closed, should be normally open. Definitely check all hoses that go to your charcoal cannister and make sure they are working and not cracked and/or loose. You may be due for a canister replacement and an evaporative emission system cleaning. Good Luck and let us know if any of this helps you out.

Check the gasket on the fuel fill cap. They crack with age and may be allowing vapors to escape as the fuel expands in the tank. This can also cause the check engine light to come on.

Could be a fuel rail leak on the line that supplies gasoline to the carb. you may not see liquid as it will evaporate on top of the hot intake.

take oil filler cap off and check if petrol smell is there. if there is petrol in oil then big problems will come ( oil will be more fluid and not pump everywhere, leading to big end failure). might be leak in petrol pump.
