Mercedes Benz repair: Mercedes E350, fuel leaks, fuel line

Question
My E350 Mercedes has a gas smell inside the vehicle while driving. It was really strong. Now it is less strong, but I can still smell it. What could be causing it?

Thanks,
Richard

Answer
check for fuel leaks .take off air air cleaner if its on top or if not take off your plastic shroud piece chances are you have a leak in your fuel line from your pump to your intake or somewhere around passenger side probably cant miss it. dont run car too long with that smell I burnt an older one up fuel got on manifold and it started on fire
