The most common cause for this condition is a leaking purge valve located under the hood. This purge valve goes bad all of the time causing a few different conditions. It could go bad causing a hard start after filling up with fuel or it could be leaking fuel vapors causing this smell inside the vehicle you are describing.
Also, be sure to check the fuel-rail dampener, around the fuel pressure line, fuel injectors and o rings VERY carefully for any fuel leaking as this can cause a gas smell inside the vehicle.
I hope this helps and have a great weekend!

Consider getting this info on ADDING Hydrogen power to your fuel. Raises fuel mileage 25% to 50%+.

Imagine if it works - raise your fuel mileage to 21+ in stop n go driving, up tp 35+, maybe 40 mpg with a steady low cruise on the highway, at 60-62 mph.
only costs $170-$200 if you can do it yourself, if you can change pcv / oxygen sensors / plugs / fuel filters, YOU can do it.
Else, pay a mechanic an extra $200 for 2 hours work for him/her to install in 45 minutes.

try the air filter first and the intake.the spark plugs then and after all go to a garage for checking compression timing and the head gasket.
Have a great weekend!

Hi Andre Strydom, I want to help you with your question, but I need more information from you. Can you please add details in the comment box? Is your engine light on? I have a good idea what is wrong
Hi Richard, no the engine light does not come on. It starts good, this morning though it backfired once. Maybe timing thats not set properly? The previous owner say the rings were replaced and she needs to go on a diagnostic machine although he is not sure about this. The car goes well and then it feels like she is flooding like a car with a carb, I just accelerates ans she moves smooth again. Ihope this gives a better indication
