Fuel filter is on the Firewall by the Master cylinder. To change it I would release the pressure from the fuel system ...by removing the fuel pump fuse. Turn the car on until it stalls ...try to crank it once or twice just to make sure it's dead. Removing the filter is pretty self explanatory after you see it . there are two hose one at the top and the other at the bottom. Just make sure not to damage the lines.
