Fuel smell - Rear quarter outside car.
I've brimmed the tank for the first time in ages and noticed a raw fuel smell around the rear quarter of the car, strongest under the wheel arch.
At first I though it was the fuel filler cap not being closed but even when fully (clicking) tightened the smell remains. A corroded fuel filler pipe also makes sense but....... the tank appears to holds pressure e.g. I get a pressure release when I open the filler cap so how can the filler pipe be leaking fuel if it's airtight?
Anybody got any ideas what could leak fuel (vapour) only when tank is over 1/2 full but not affect the air tightness of the tank?
