Just a little confused as your first entry states "back into the tank", and that's what I suspect only because there is no noticeable odor under the hood.

There appears to be an issue with the fuel draining back when the vehicle sits overnight preventing a quick ignition in the morning. If the key is turned just to the on position for a few seconds, the car starts right up, otherwise you would have to crank it for a while. I assume the fuel is draing backwards in the line overnight. Is there an anti backup valve to prevent this, or is the fuel pump losing prime somehow?
