I haven't seen anything from '09 owners yet, but '07 and '08 cars will hold at least 12 gallons, probably closer to 13. That's a whole lot more than just the filler neck! I suspect that the location of the tank under the front seats is at the root of it; perhaps the filler goes into the side of the tank instead of the top. One of these days I'm going to pop that cover off underneath the car and have a look.

Also, modern fuel systems are sealed. They do not vent anything at all to the atmosphere. There is a canister of activated charcoal somewhere in your car that captures fumes and recirculates them back into the fuel delivery system. Folks worry that "hyperfilling" Fits may harm that system; however despite the fact that quite a few people "hyperfill" their Fits, there have been exactly zero reports of damage.
