How to replace the fuel filter on Kia Optima?

This procedure applies only to 2001 through 2006 four-cylinder models and 2001 V6 models, which use an external fuel filter; on all other models, the fuel filter is an integral component of the fuel pump assembly. First, relieve the fuel system pressure and disconnect the cable from the negative terminal of the battery. Place rags or a drain pan under the fuel filter. Raise the rear of the vehicle and support it securely on jackstands, noting that the fuel filter is mounted near the left front corner of the fuel tank. Loosen the fitting nuts on the fuel lines while holding the fuel filter fittings with a wrench. Remove the bolt securing the filter mounting strap, then take out the filter. Installation is the reverse of removal, using new sealing washers and tightening the fitting nuts to the specified torque. Finally, reconnect the battery, turn the ignition key to the On position, and check for leaks.
