FASS Fuel Systems for Performance and Efficiency

Wherever you want to go, FASS will take you there. FASS fuel systems are designed to remove contaminants from your diesel fuel to reduce unnecessary wear on related components, such as your fuel injectors. Unlike conventional fuel systems, diesel enters your FASS fuel system under a vacuum and exits under pressure. FASS removes dirt and other debris before it enters the electric fuel pump.

From there, the fuel enters FASS's patented extreme water separator that removes 99% of water molecules present in your system. Air and vapor are subsequently returned to the fuel tank while the clean fuel is sent forward to your engine for smooth, efficient combustion and maximum performance.

FASS Diesel Performance for GM, Ford, Dodge and More

When it comes to achieving the best performance from your diesel engine, getting the most out of your fuel system is a great way to improve performance and fuel economy. For FASS diesel fuel systems, you can shop by vehicle manufacturer to narrow down your selection and find all compatible components. FASS manufactures fuel systems for all of the major labels, including:

  • Ford Powerstroke
  • GM/Chevy Duramax
  • Dodge Cummins
