If you drive a 2011-2014 GMC/Chevrolet with the Duramax diesel engine upgrading your fuel filtration and delivery will triple the life of the injection system, increase MPG & power, provide exceptional extreme cold weather operations and more.

That’s exactly why we engineered the Titanium Signature Series Fuel System, to outlast and outperform anything else on the market. This Fuel System is designed to provide the purest possible fuel to your Duramax and built to outlast it.

Peace of Mind, Efficiency, Power

Advanced Filtration Technology

FASS doesn’t just move fuel – we filter it better than anyone:

• Water Separation: 3rd-party proven to eliminate over 99% of water.
• Air/Vapor Removal: Eliminates entrained air and vapor that damages injection systems and reduces power/efficiency.
• 2 Micron Absolute Filtration – Microglass: Removes debris smaller than OEM filters can catch.
• Mass Flow Return (MFR): Constantly “polishes” your diesel by sending unused fuel back through the filters, so your tank always holds clean, conditioned fuel.
