The fuel filter is located on the passenger side of the car just behind the rear axle, and is partially covered by a rubber boot. You can use either use a floor jack under the rear differential housing to raise the car up and lower it onto jack stands (a bit tricky), or back the car up onto ramps (which I prefer). After that, you have to remove the boot (three 10mm screws),pinch off the life from the tank (unless you like bathing in gasoline), and then disconnect the fuel filter (fitting at either end, filter held in place by a clamp). Please note that there are hex-shaped fittings on either end of the filter to hold it in place while you undo the fittings, otherwise you can damage the lines. It's actually a straightforward job as long as you have a decent set of metric tools.
