Changing a fuel filter is not hard, but it's more involved than an oil change. It is a lot easier to do if you put the car on ramps or safely support the driver's side with a jackstand.
1. Relieve fuel pressure by pulling the fuel pump fuse while the engine is running. Turn off car.
2. Raise car using the safe method of your choice (optional).
3. Locate plastic cover for fuel filter on the driver's side underbody.
4. Remove plastic cover (just a couple of screws, IIRC)
5. Get some rags ready for fuel spillage.
6. Locate the fuel filter. Identify the connectors that are used to connect the fuel filter to the fuel lines. There is more than one type of connector. One type can be released with needle-nose pliers. The other type needs a special tool. My 05 V6 has the connector that can be released with needle nose pliers.
7. Ask yourself: "do I really know how to release this fuel line connector?" If the answer is no, then stop. You'll end up with a fuel leak and a repair bill.
8. If the answer is yes, release the connectors and remove the old filter.
9. Look at the new filter. It probably has an arrow telling you which way it should be facing. The arrow is in the direction of fuel flow (towards the engine)
10. Install the filter. Make sure the connectors snap back into place.
11. Lower the car. Put the fuse back in. Turn the key to "on" for 30 seconds to pressurize the fuel system. Check for leaks.
12. Install filter cover.
