FUEL FILTER, WATER SEPARATOR CARTRIDGE

This is a fuel filter water separator cartridge for diesel engines. It traps water and microscopic particles down to 7 microns to keep your fuel injectors clean and prevent engine damage. Replace it when your fuel system maintenance is due, typically every 15,000-30,000 miles, or if you notice loss of power, rough idling, or a water-in-fuel warning.
