How To Change a Honda Civic Fuel Filter

A fuel filter is a vital part of a car’s engine, because it aids in screening out dirt and rust particles from the fuel line. Usually, fuel filters are constructed in the form of cartridges, with an installed filter paper. Fuel that is not filtered may contain contaminants such as dirt, dust or paint chips that may have entered the tank during refilling. Rust may also join with the unfiltered fuel because of the moisture in the steel tank.

Why change your filter? Once these substances enter the vehicle with the fuel, it must be removed or extracted before the fuel enters the system. The substances can cause early wearing-out of the injectors and the fuel pump, which can cause your engine to stall. Fuel filters are capable of improving the performance aiding the rapid and more effective burning of the fuel because of the fewer particles the fuel has in it.

Know what the filter looks like. A fuel filter on a Honda Civic is a miniature cylindrical piece that is often found resting at the side of the master brake cylinder on the firewall. Normally, the fuel filter is made in either black or silver colors, made out of metal. It is designed to segregate harmful particles from the fuel, keeping it from sedimentation and from entering the system.

Trace the fuel filter. Ordinarily, it is found near the driver's side of the engine bay. Once you have the filter located, unfasten the bigger bolt that located on top of the fuel filter. Use an open-ended wrench to loosen this bolt. Separate the fuel line and the crown of the fuel filter. However, keep the copper washers that are connected to the fuel line.

Make sure that the vehicle’s engine is turned off. Remove the key from the ignition for safety. This should be done prior to the whole operation to ensure your safety and to avoid complications and injuries.

Use WD-40 to loosen the bolt located at the lower part of the filter. Do this in order to loosen the bolt a bit before completely removing it using the open-ended wrench. Detach the other fuel line. You may now disconnect the filter bracket using a socket wrench to undo the bolt. This gives you access to the filter. Get rid of the old fuel filter inside the fuel filter bracket.

Get hold of the new fuel filter and slide it in the filter bracket. Then, reattach the bracket to the firewall. Reattach all fuel lines and bolts that were removed before. Tighten all the bolts to secure the bracket and keep the fuel lines intact.

Start the fuel pump and put pressure on the fuel line. Make sure there are no leaks at both top and bottom gears. If there are leaks present, turn off the ignition and remove the filter assembly where the leaks are found. Also test the condition of the washers and seats to ensure all pieces are clean and smooth. Reassemble the filter and recheck for leaks.

Changing your car’s fuel filter is usually part of its regular maintenance. Never ignore or put off simple processes like this, which only takes you less than an hour. Keeping your car in its optimum condition is always the best way to ensure your safety while driving.
