Please Note: This Fuel System REQUIRES aftermarket tuning to be compatible with this vehicle.

If you drive a 2020-2023 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 PLUS 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.

The Titanium Signature Series PLUS Fuel System is designed for customers who want all the performance and
protection of a FASS Titanium Signature Series fuel system with upgraded black anodized ORB (O-Ring Boss)
fittings at the filter base and all black anodized AN style fittings throughout.

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.

Key Benefits:

• Improves Reliability: Triples injection system life
• Maximized Horsepower: Stronger throttle response, improved fuel atomization, restored injection timing, resulting in your engine becoming much more balanced
• Optimized MPG: More efficient/complete combustion (results will vary)
