The supply of Clean, uncontaminated fuel is key to maximum fuel system performance and longevity for modern diesel engines. Without high-quality fuel filtration and regularly scheduled service, fuel contamination can lead to costly repairs and engine downtime. A fuel cleanliness study found that more than 50% of fuel used worldwide does not meet the suggested industry cleanliness levels. Fuel injection system suppliers today require that fuel entering the fuel injection system have ISO cleanliness levels as low as 11/8/3*. This FASS 150 Series Replacement Diesel Fuel Filter Set with the FASS FF-1003 and FS-1001 filters ensures the supply of clean fuel to your fuel injection system by removing the suspended contaminants and water-effective fuel/water separation with high quality. Filtration reduces component wear and creates optimized fuel atomization and engine power.

FASS 150 Filter Set 3 Micron Replacement Fuel Filter Change intervals are between 15,000 to 30,000 miles based on Fuel Quality. In addition, using Bio-Diesel, Vegetable Oil, and Blended Fuels can significantly reduce the life expectancy of your FASS 3 Micron fuel filters. 

KLM Performance strongly recommends keeping a spare FASS set of replacement filters in your truck. Having an extra set of filters onboard is cheaper than calling for a tow.

FASS has now discontinued the FASS FF-1003. KLM Performance supports our customers with this replacement diesel fuel filter that offers a 3-micron filtration level to help preserve the integrity of your entire fuel injection system

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 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.
