With any engine, it is imperative to keep up on maintenance to avoid a potential catastrophe in the long run. One often overlooked area of maintenance is that of the fuel filter. Sure, the job of the fuel filter is to keep clean fuel entering the combustion chamber, and particles out. But when the fuel filter begins to get clogged, it will drastically hinder fuel flow, meaning that the injectors cannot fire properly, reducing the overall power and fuel economy of your engine. This simple task if gone overlooked can not only rob you of power, but harm your injectors and other vital engine components.
