This FASS 150 3 Micron Replacement Filter Set works on the following FASS Fuel Systems:

  •  FASS 150 Series Pumps
  •  FASS HD Series Pumps
  •  FASS Versatile Series pumps.

The FASS FF-1003 is a replacement diesel fuel filter that offers a 3 Micron filtration level to help preserve the integrity of your entire fuel injection system.

NOTE: Please make sure you have ordered the correct FASS filters for your fuel pump. Once a filter protective seal has been opened it is no longer a returnable item. If you have any questions regarding the filters required for your Fuel Air Separation System please contact us for assistance!

The FASS FS-1001 has now been discontinued by FASS. KLM Performance will now ship you a Fleetguard FS1001 replacement water separator filter. This FS1001 offers a 10 Micron filtration level that removes both the entrained and emulsified water from your diesel fuel. KLM Performance recommends regularly draining the FASS FS1001 water separator filter to remove the water from this water separator filter. By draining this filter you will increase the life expectancy and avoid fuel-related problems.

Periodically removing the water from the FASS FS1001 filter will help to prevent freeze-ups in your vehicle fuel system during the winter months. FASS pumps remove entrained air, water, and fuel contaminants and clean filters are a must. For the best engine performance possible, please remember to change your FASS filters at regular intervals. FASS Fuel Filter Change intervals are between 15,000 to 30,000 miles based on the quality of the diesel fuel you are using. 

Remember to keep a spare set of FASS 150 Series Replacement Filters in your truck at all times. It is far cheaper to have an additional set of FASS 150 Series Replacement Filters in your vehicle then the cost of calling for a tow.

NOTE: The use of Bio-Diesel, Vegetable Oil, and Blended Fuels can significantly reduce the life expectancy of your fuel filters.
