Smell of gasoline in the morning that goes away after 10 min of driving
Hi,
For the last 3 days, when I entered the car in the morning, there is a smell of gasoline. I checked around and did not see any leak. After driving for 10 min, the smell goes away.
I searched on internet. Most suggested it's some leak in the fuel system
What could I do to check?
thanks

It's a known issue, leaks at the fuel hose fitting at the top of the engine where it connects to the fuel pump. Goes away when the engine warms up. I've attached a warranty extension originally posted on this forum by NDR.
I fixed mine the other day by replacing a defective or poorly installed clamp, I'll post pics of what I found/did later today in another thread so other DIY's can see if the same scenario applies to them. I'm out of the warranty window so I couldn't have the dealer remedy, if within the warranty window I would have certainly let them fix it.
