Do you always smell fuel vapors, or only after filling the tank? A common problem are bad seals on the fuel pump and sender units. This likely won't cause hard starting, though. If you smell fuel vapors all the time, I suspect a fuel line leak, and that can be very dangerous - you should get a qualified mechanic to look at this ASAP.
