I just recently did a fuel pump replacement in my SVT Contour through a hole in the floor. Ford provided a small access hole, but it's not large enough to remove the pump assembly from the tank, so you have to cut and patch. http://s301.photobucket.com/albums/nn78/gmorrell_1959/Contour Fuel Pump Replacement/ There must be some sort of perverse natural law that causes your fuel pump to fail completely tits-up dead right after the tank is filled, as this is what happened to me. I'd have no problem doing a through-the-floor pump replacement in my SHO. Just seal it back up well and it's not going to be a problem.
