Remove fuse #8 in the fuse box under the hood to disable the fuel pump and open the gas cap. Disconnect the battery also for safety precautions. Start the engine and let it die. Take the plastic clamp off, might break and screw might be frozen depending on what part of the country you're in. Take the plastic top off the shrader valve and depress it to relieve the pressure, small amount of gas will come out. Then using needle nose pliers, depress the plastic clips on the inlet and outlet on the filter. Again, once removed, will lose some gas, take note of hose was inlet and which is outlet. Replace in reverse order. Your plastic fuel filter clamp may be broken like mine was, zip ties work wonders until you get a new one.

Where can I locate the fuel filter on a 2002 evony

I believe the fule filter is underneath the vehicle just on the inside of the metal structure rail. Hmmm. I guess I should say that if you opened the front door and reached down under the rocker panel you should be able to touch it. This description is just to give the general area, please do a visual to locate the fuel filter in this area.

good luck
