Fuel filter is located under the brake booster/rear of air filter box area on the driver's side chassis leg. Tools need to change it are a 17mm socket for the top banjo bolt fitting and a 14 mm flare wrench for the fuel line coming into the bottom of the filter. Try loosening this first, if it does not loosen stop, it will strip the head of the fitting. the filter bracket has two 10mm head bolts securing it to the chassis leg. The filter is a little difficult to change so see if it is really a job you want to do yourself.
If you are facing the motor it will be hanging on the fire wall right up front a proper pipe fitting wrench will be needed because these are generally a bitch to get off. You should see where the gas line comes in on bottom and goes out to fuel rail. Dont forget if car has a lot of miles on it and you have never changed the fuel pump in the tank there is a sock filter over fuel pump probably a good idea to replace as well.
