Signs that a Ford may need a fuel filter replacement include engine lag, stalling or hesitation. Clogged fuel filters are common and many people can perform a fuel filter change themselves.
A fuel filter's job is to remove dirt and debris from the fuel tank, preventing contaminants from finding its way into the engine. Over time, this dirt collects in the filter and eventually, the filter becomes clogged. Many auto manufacturers recommend changing the fuel filter every year. Drivers who regularly use cheap fuel or spend a lot of time driving on dirt or gravel roads may need to change the filter more often.
