Hi. My Zed leaks an embarassing amount of fuel very suddenly, when you hit the very top of the fill tube. Until then everything is fine. I like to fill it up all the way. It is not until you get to within a couple of inches of the top of the filler neck, however, that suddenly my car pisses it's pants. Come to think of it, is has always been when a Mustang 5.0 or a Grand National pulls up alongside it. yuk, yuk. Anyway, I cannot find the source fo the leak. ANybody know??
