The NAPA in-line fuel filter is the replacement fuel filter for all Transfer Flow in-bed auxiliary fuel systems. The fuel filter should be replaced within 3 to 6 months after installation, Transfer Flow includes an extra filter with your initial purchase.
Transfer Flow recommends the filter be replaced every 12 months on vehicles that see normal use. If the vehicle is operated in dusty conditions or driven more than 20,000 miles per year, the filter should be changed every 6 months. Vehicles traveling outside the United States and Canada may be exposed to filling stations containing elevated levels of contaminants. It may be wise to carry spare filters when traveling outside of the country.
