Note that this special coverage expires at the end of THIS year and vehicle must have less than 150,000 miles on it. To see if yhours is leaking, laydown under the drivers side right in front of the rear fender well/tie and look up at the tank. If its been leaking you will see small water lines where the filler tube enters the tank. you should also smell fuel when you drive it. It will only continue to get worse over time, so you may want to try and get it done before it runs out. I also replaced fuel pump when they did it as there is no labor charge since they have to remove it anyway.
Heres the info on it. Hope this helps.
This is the site address and these two bulletins are about it. They are located about 3/4 of the way down.
