On my 1998 LaSabre, the fuel filter is located on the passenger side, under the rear passenger seat, close to the door. It is easy to see simply by looking under the vehicle without having to jack it up. Mine is about 8-10 inches under the vehicle from the outside edge. Everybody told me to look under the drivers seat also, maybe that was a different year model (?). Hope this helps.
