Does anyone else find their car has a strong odor of petrol when the car has been parked for a while and the tank is full?

 

I've only had to fill up my car three times in the year since I got it (thanks to mostly running on EV) but I get this smell when the tank is full. It goes away after I drive around, but as long as the fuel gauge shows all the bars, I can smell petrol when I get back in the car. My driveway has a slight slope upwards from the street, and I noticed it is not as bad when the car is parked on a level surface.

 

I'm getting it serviced next week, but wondered if anyone else had this experience?

Eliminating obvious of bringing fuel in with you on your feet etc…

 

given difference with a slope, my gut is thinking small leak from something. Definitely get it checked at the service. Of course they will likely say nothing to be found, I’d say it’s unusual, one clip missing and water aka fuel always finds a way.

Had this with a Punto, was a split breather hose IIRC.

@Kiwiana - I think that both @ColinD and @AnnoyingPentium have plausible theories, most likely near the fuel tank either way.
