How can you change a fuel filter in this car? on 1994 Chrysler Concorde

The car turns over, so the battery, alternator, and starter are fine, and we just replaced the spark plugs, but now it won't start. We think it is the fuel filter, but we are not sure, how can you be sure it is the fuel filter? And do you have any insite on how it can be fixed.

The fuel filter is mounted to the frame rail, in front of the fuel tank. Test fuel pressure with a guage....should have about 48psi.
