Mk IV Golf - Petrol Smell

[groomi]

My Wife's Golf has started to smell of petrol while parked up. It stinks before driving off, but doesn't seem to smell while driving. Fuel consumption doesn't seem to be any different, so it certainly isn't leaking anything significant.

It ran out of fuel a few days ago and the smell has started since then - could it be connected in any way?

Does anyone know if it's a common Golf fault? If so, I'd rather fix it myself than take it to a garage.

Cheers Guys,
I haven't had chance to look at it yet, but interestingly it smelt much less today.
