Question about 2002 Ford Taurus
If you can not find a fuel leak under hood, then check for a bad fuel pressure regulator. if it goes bad it will emit gas fumes under hood. is the check engine light on!! if so it may be the regulator or another leak. also check the evap system, could be a bad or broken hose ( underhood ). check all fuel lines from front to back.

Tips for a great answer:
P0443 The fuel vapor canister reduces that gas smell on hot days outside/inside of car. The fuel vapor canister fillers bad smells from gas tank on hot days when the gas expands and burps fumes through carbon canister filter. From the canister (gas vapor fumes) goes back into the engine to be burned again...it's a closed loop for vapors to be recycled though engine. Don't worry, once the carbon canister dries out and no longer flooded with raw fuel the code should go away...just don't let the top off fuel tank back flow into the 'Evap emission control' carbon filter near the top and close to the gas cap...:)
