A blocked fuel filter affects the engine’s ability to draw fuel. The vehicle is likely to feel sluggish and, in worst case scenarios, the engine may fail to start. Fuel filters must be replaced in accordance with the vehicle manufacturer’s service schedule, usually at around every 30,000 miles or two years.
