Maintain the lift pump on your 1999-2003 Ford 7.3L Powerstroke with new Fuel Filters. In some applications you can cross-reference a replacement filter to your existing filter due to availability to increased filtration. Lift pump fuel filters are available in multiple micron ratings depending on the manufacturer of the pump. Find the replacements you need for your AirDog, FASS, Fuelab, Aeromotive, AFE, or other aftermarket fuel system.
