Just sharing this as I noticed I wasn't the only one with this smelly issue.
A couple of months ago I noticed a strong smell of petrol outside, and sometime inside, after a fill up. It would slowly dissipate as the tank emptied, but always came back after a fill up. My first searches all pointed to the EVAP system (the valve, or canister), or maybe the fuel cap...sometimes a cracked fuel filter hose or filler hose. I contacted a couple of garages who didn't want to go on a diagnosis hunt without any fault codes to show them the way, so today I decided to start tearing things apart myself.
Once I got the rear seats out and access to the fuel pump, there was a puddle of petrol in the bowl of the tank where the fuel pump sits. ALSO, the fuel pump collar was so loose I had to turn it practically 180* to get the small arrow to the "Min" marking.
I've only owned the car for just over a year, so no ideas how this could happen...until I remembered reading about a fuel pump recall. My best guess is it was taken in for the recall by the previous owner and the collar was never fully tightened after the pump was replaced.
If other owners have had the same shoddy workmanship, I offer this as a possible solution. Getting to the pump to check was a piece of cake, too.
