The fuel filter is located just in front of the fuel tank in the center. To change it, simply pull out the two plastic clamps that hold it in and remove the hoses from the filter. Try not to break the clamps, but if you do, there are new ones supplied with the filter. Some other advice. Wear goggles!! fuel will drip down on you when you remove the hoses. Also be sure you put the filter in facing the correct direction. Put the new filter on facing the same way as the one you took off. There will be an arrow on it showing the way fuel will flow. If you forget how the old one went on, you can trace the hoses to see what way the fuel will flow. Also, have towels with you for when the fuel drips out. Some people cut pressure to the lines. I don't bother because you will still have fuel drip out. I let the car sit for a day before doing this.
Good Luck
