Unlock Superior Diesel Performance With FASS Fuel Systems

Wherever you want to go, FASS fuel systems will take you there. FASS Diesel Performance is your go-to brand for unmatched performance, offering a comprehensive solution for diesel fuel filtration and air separation. Unlike conventional fuel systems, diesel enters your FASS fuel system under a vacuum and exits under pressure. This innovative approach ensures your fuel is cleaner and free from contaminants before reaching vital components like fuel injectors.

FASS fuel systems go the extra mile to protect your engine. By removing dirt, debris, and 99% of water molecules through FASS's patented extreme water separator, the system dramatically reduces wear on your engine's integral parts. Air and vapor are rerouted back to the fuel tank, leaving only clean fuel to be sent forward to your engine. The result is smooth, efficient combustion and maximum performance – something every diesel engine user can appreciate. Reliability and performance are at the heart of every FASS fuel pump, ensuring that your diesel engine performs at its best and lasts longer.

FASS Diesel Performance Systems for GM, Ford, Dodge, and More

When you want to achieve the best performance from your diesel engine, a FASS fuel system is a great way to improve performance and fuel economy. Whether you need a FASS replacement pump or an entire FASS mounting system, you can shop by the vehicle manufacturer to narrow down your selection and find all compatible components.

Whether you own a Ford Powerstroke, a GM/Chevy Duramax, or a Dodge Cummins, FASS has designed systems that are compatible and optimized for your vehicle's unique specifications. FASS Diesel Performance manufactures FASS fuel systems for all major labels, including:

  • Ford Powerstroke: Enhance your Powerstroke's fuel efficiency and engine longevity with a FASS fuel system tailored to meet Ford's engineering standards.
  • GM/Chevy Duramax: A FASS fuel system for Duramax trucks is designed to offer superior fuel filtration and air separation, maximizing your Duramax engine's performance and reliability.
  • Dodge Cummins: Dodge owners can experience the remarkable benefits of a FASS diesel fuel system built to complement the Cummins engine, offering exceptional fuel economy and reduced engine wear.
  • & More

By shopping for your FASS fuel system based on your vehicle manufacturer, you're taking a strategic step towards optimizing engine performance, extending the life of your fuel injectors, and improving overall fuel economy.
