Ksssschneide: The fuel filter is located underneath the car on the left hand side of the fuel tank. It is secured by a bracket which I believe is a 10mm socket size.
You will need to discharge the fuel pressure from the system.
You can do this by going in the trunk where you can access the fuel pump harness. Disconnect it then start the car. Continue to start it until it no longer starts. At that point all the pressure is out of the system.
The fuel filter is directional.PAY ATTENTION to that. There is a fitting on each end of the filter which you can remove with a wrench. Remove both ends and have the other filter ready to install. NOTE>>>> In some cases, fuel wants to run down, Be expecting it. It is not comfortable in the arm pits!
Put it back together, make sure you are careful to get the lines threaded part way on the filter before you start trying to tighten it.
This is to avoid making the mistake of cross threading it! Tighten the lines, Clamp it in place, reconnect the electrical connector and start the car. Check for leaks. Keep in mind this is a high pressure system, so you will have anywhere from 30-60 psi. If you have a leak it can spray pretty far.
Good luck!

Do you have the 4 or 6 cylinder?
1.6L (VIN 3), 2.0L And 2.7L Engines

  1. Before servicing the vehicle, refer to the Precautions Section.
  2. Relieve the fuel system pressure.
  3. Disconnect the negative battery cable.
  4. Remove the rear seat retainers (clips or catches) and rear seat cushion.
  5. Disconnect the harness connector from fuel sender.
  6. Remove the fuel tank module screws and the fuel sender and filter.
  7. Installation is the reverse of the remove procedure.

1.5L, 1.6L (VIN 5), 1.8L And 2.4L Engines
  1. Before servicing the vehicle, refer to the Precautions Section.
  2. Relieve the fuel system pressure.
  3. Disconnect the negative battery cable.
  4. Disconnect the fuel lines from both ends of the fuel filter. Plug the lines to prevent leakage.
  5. Remove the bracket retaining nuts and bolts, as necessary.
  6. Remove the filter and the mounting bracket.
To install:
  1. Install the filter in the mounting bracket.
  2. Connect the fuel lines to the filter.
  3. Install the bracket nuts and tighten to 9.5 ft. lbs. (13 Nm) for 1.5L, 1.6L, 1.8L and 2.0L engines. For 2.4L engines, torque the nuts to 18-25 ft. lbs. (25-35 Nm).
  4. Connect the negative battery cable.
  5. Run the engine and check for any fuel leaks.
I can give you exploded views of the fuel filter/fuel system if you provide me with an email address.

I had to look for mine last night. The filter is in the gas tank. Just pull out the carpet in your trunk and you will see the access.

My 2004 Optima did nt have filter exactly. There is only a filter bag type device on the inlet to the fuel pump. The fuel pump is located in the gas tank and is accessed by rolling back the carpet in the trunk... I have 165K on mine and never changed this filter. No parts listed at NAPA or other store for filter. Just put some injector cleaner into the gas tank every mont and should be fine
