We mentioned earlier about how the fuel filter protects your engine from harmful sediment and particles in the gas. The fuel filter catches any particles or debris that would be harmful to the engine and keeps it trapped in a canister, much like your oil filter does.
If the filter hasn't been replaced in a while, then it's a good idea to change it to keep the engine running smoothly. If your filter is easily accessible, this repair won't be too difficult, but some filters may be hard to reach. If you can't access your car's fuel filter, take it to a mechanic to be replaced.
A new fuel filter will keep the gas flowing into your engine clean. Your engine will have less build-up inside of it and will last longer if it's not working as hard to burn the fuel it's getting.
