Tony, the hoses leading from the fuel tank are notorious for leaking after your car gets
older.  Open the trunk and remove the carpeting and then the inspection plate.  You will
see the hoses leading from the tank to the fuel injection system.  There are two hoses,
one for the FI system and a return hose.  Both hoses should be checked for wear.  You
may have to use a mirror to see all of the hose above the fender well of the passenger
wheel but the damage is nearly always visible and the odor will be very strong if the
leak is there.  Removal and replacement are a slight challenge but not anything to
concern the DIY.  Make sure you get the correct size hose and replace both of them while
you are there to prevent a similar trip next year or sooner.
