I have quite a strong smell of petrol around my car when it has been stood for a while. Can't smell it while driving or when I get out. Seems to be a lot worse when I have been for a drive then come back to the car after about half hour it's really strong. I haven't noticed any leakage on the floor and my petrol doesn't seem to be going down any quicker. Has anybody had this problem? Not sure if it was common and easy to fix.
