A clogged fuel filter restricts fuel delivery flow, forces your electric fuel pump to work twice as hard (leading to premature pump burnout), and causes engine spluttering under high-load acceleration. While Volkswagen recommends changing the fuel filter every 40,000 miles (60,000 km), it is frequently neglected by previous owners. Because the fuel filter configuration is … Read more
