I think I might do some PM. Where is the fuel filter on a 98 Deville Concours?

 

The fuel filter on a 4.6 deville is located on the drivers side bottom UNDER the car right in front of the rear wheel right under the rear passanger door. First under the hood is a black fuel line and there is a valve like the kind on your tires to inflate them you have to relieve the built up gasoline that is in the line because if you dont when you try to remove your filter the preasure in the line is going to spray you with gas all over your face it happens remember its a fuel injected car every time you turn the key the pump builds preassure in the line put a rag under the valve this will keep gas from going all over the place after there is no preassure you are ready to start. ok now The fuel filter has a soldered nut this wont move so all you have to do is put a wrench on it and the fuel line has another nut this one does turn so put a wrench on this one and holding on to the wrench that is soldered to the body of the fuel filter turn the one connected to the fuel line COUNTER CLOCKWISE the nut connected to the fuel line sometimes gets rusted so WD-40 prior to starting the removal or some other type of rust penetration might help. the other line just has a clip. press the clip and twist and pull the filter off. To get a better idea look at your new filter and it will all seem clear. Hope this will help you.
