Required Tools: New fuel line washers, new fuel filter, open end wrenches, eye protection, and rags

Your fuel filter is a filtration system on your fuel line that works to filter out rust, dirt, and other contaminants and particles from your fuel. These contaminants can build up over time in your fuel line and reduce the amount of fuel that can get to your engine, lowering your fuel efficiency and horsepower. It can be even worse if these contaminants reach your engine as the particles will solidify into sludge and can hinder your engine’s ability to start. You should change your fuel filter every year. Come into your local U Pull & Pay today to get all of the parts you need to do this simple maintenance job.

  1. Start by first relieving the fuel system pressure. Locate the fuel pump on your fuse box, start your car, and with the engine running pull out the fuse or relay. When the engine dies, you know you have pulled the right fuse.
  2. Get two open-ended wrenches and disconnect the fuel lines from the fuel filter.
  3. Put a rag over the fitting to protect yourself against any residual pressure that may still be in your fuel lines.
  4. Keep the wrench that is on the oil filter side stationary and slowly turn the other wrench counter-clockwise until the bolt comes out.
  5. Slide the fuel line off the bold and set the bolt aside safely.
  6. Repeat steps 3-5 again on the other side of the fuel filter.
  7. Take out the old fuel filter. Most fuel filters are attached by a simple clamp system that can be separated using a flathead screwdriver. Use your rag to grab and wrap up the old fuel filter as it may still have some fuel left in it. Safely dispose of your old filter, keeping it away from extreme heat and fire.
  8. Change out your fuel filter washers, which are located on the bolts that connect the fuel filter and fuel lines. Make sure you use the right size and match them up correctly.
  9. Put your new fuel filter in place and clamp it in place by reversing steps 8 and 7.
  10. Once you have installed your new fuel filter, reattach the fuel lines and return the fuel pump fuse or relay before you start the car again.
