Well, if it was draining the excess into the rear fenderwell, you'd have
fumes all the time, just strongest when you filled up... after all, get it
on your hands and wipe it off... the oder is still there...

One thing I don't hear them advertising much is if your in a area with RFG
gas, it's supposed to cause fuel lines to become brittle... but only affecting
cars 10 or more years old...

Bullet #3 says;
* The rubber that is used in fuel system parts, such as seals and hoses,
 may shrink, swell, or lose strength when exposed to RFG. This reaction
 could cause fuel system leaks in a very small percentage of vehicles.
 Because RFG differs only slightly from the gasoline that you have used
 in the past, auto manufacturers do not expect RFG to cause fuel system
 leaks in the majority of vehicles, particularly newer vehicles. However,
 if your vehicle is older (more than 10 years old) or has high mileage (more
 than 100,000 miles), you may be at greater risk of developing a fuel leak.
 Because fuel leaks can cause vehicle fires, Chevron recommends that you
 consult a qualified auto repair technician to discuss whether your fuel
 system parts should be checked for repair or replacement. If you suspect a
 form of leakage, which can often be detected by smelling gasoline at times
 other than when fueling, consult a qualified auto repair technician
 immediately. Do not drive a vehicle with a fuel system leak.--
