Changing your fuel filter is fairly straightforward and takes about a half an hour. It costs around $20 to do on your own (the price of a new fuel filter and washers). Here’s how to do it:
1. First and foremost, relieve the fuel system pressure by locating the fuel pump fuse on the fuse box. Start your car, leave your engine running, and pull the fuse or relay out. You will know you have done this right if your engine dies.
2. After relieving the fuel pressure, you can use two wrenches to disconnect the fuel lines from the fuel filter. Be sure to use a rag to cover the lines after you get the wrenches in place just in case there is still some pressure in the lines. Hold the wrench that is on the filter while turning the other wrench until the bolt comes out.
3. Slide the fuel line off the bolt and repeat on the other side.
4. Remove the old filter. You may need a flathead screwdriver to do this. Be careful as gas may still be in the old filter.
5. On the bolts you removed in steps 3 and 4, there will be washers. Remove the old washers and replace with new ones.
6. Install the new filter by doing the opposite of what you did to remove the old one. Put the fuel pump or relay back on before you try starting your car.
