So I put £30 in the zed before going to @t-tony at the weekend and soon noticed a very strong fuel smell, it became apparent that it was when I was cornering particularly on left handers, this went on all day, I kept checking the car under the engine bay and all around, on the way home I went into the red and still got the smell, stopped at a fuel station and put £10 in, drove 15 miles home with no smell at all, took the car out yesterday to double check, threw it round lots of left handers and still no smell whatsoever, I'm a bit stumped what caused it as I checked the filler cap and thats the only thing that changed when I fueled up, my MPG was terrible as well so I was definately losing fuel somewhere.
