Download Product Manual

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

If you drive a 2017-2019 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

Supports Stock & Modified Duramax: Plenty of fuel for stock and modified GM/Chevy.

Injector Protection: Will triple the life of your injectors and injection pump.

FASS Filtration: Optimizes combustion, restores HP, maximizing MPG (results vary).

Limited Lifetime Warranty: Register your FASS system, and you’re covered.

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)

Peace of Mind: The Extreme Water Separator acts as a fail-safe in cases of extreme fuel contamination, preventing thousands of dollars in repairs,
