i just did my fuel filter on my 03. the fuel filter is located right behind the gas tank. check right behind it and it should be up right next to the floor panels. before you attempt to change it, disconnect the negative cable from the battery, take off the gas cap, and bleed the system. to bleed the system, take a very small screw driver and cloth, go to the motor. where the system gets bled, which is on the fuel rail, next to the power steering reservoir, take the cap off and very softly stick the screw driver with the cloth on it and youll start to hear the hissing. no back to the filter, you have a clip and a bolt that hold it in. the clip is for the line that runs from the fuel tank. the bolt is to the line that runs to engine. twice the filter a little bit, so it relieves a little more pressure (if theres any). be careful cause a little fuel will spill out. start with the clip (which is pretty easy). after unclipping it, try the bolt which will be a huge pain. it has an arrow on the new filter (youve said you changed this so i dont think youll have much of a problem. when done, bolt it back up, then clip it, then make sure the cap for the fuel rail is on, connect the battery and close the gas cap. the pressure will built back up and bam your done. good luck
