FASS Titanium Signature Series PLUS 100GPH Fuel System for GMC/Chevrolet 2001-2010 Duramax 6.6L (TSPC10100G)

Product Manuals

If you drive a 2001-2010 GMC/Chevrolet with the Duramax diesel engine, upgrading your fuel filtration and delivery WILL TRIPLE the life of the injection system, increase MPG and power, and provide exceptional extreme cold weather operation.

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

The Titanium Signature Series PLUS is our premier fuel system for pickup applications, combining high-flow performance, advanced filtration, air/vapor separation, and upgraded components in one complete system. Its steel bracket design provides superior stability while allowing the pump to tuck closer to the frame for better clearance and reduced visibility. The PLUS Series flows up to 290 gallons per hour through 1/2-inch ports and 1/2-inch fuel line, with larger fuel-line configurations available on high-flow applications, and accessory ports allow the installation of heater options for extreme cold weather operation.

The PLUS Series also incorporates an integrated Heat Sink: ORB fittings and 6061 aluminum black anodized fittings pull heat away from the motor, reducing operating temperature and thermal stress. The Heat Sink reduces motor temperature by 20°F or more, further extending the life of the million-mile motor and maintaining consistent performance under demanding conditions. Black anodized ORB (O-Ring Boss) fittings, 6061 aluminum black anodized AN fittings, and black fuel line give the system an ultra-clean installation.

Without proper fuel filtration, diesel injection systems are prone to excessive wear that can cost thousands. The Titanium Signature Series removes over 99% of the water from your fuel along with air, vapor, and debris down to 2 microns absolute, delivering clean, conditioned fuel to your engine at a consistent pressure.

Peace of Mind, Efficiency, Power

  • Supports Stock & Modified Duramax: Plenty of fuel for stock and modified GMC/Chevrolet trucks.
  • Injector Protection: WILL TRIPLE the life of your fuel injection system.
  • FASS Filtration: Optimizes combustion, restores horsepower, and maximizes MPG.
  • 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: Extreme Water Separation Technology, third-party proven to eliminate over 99% of free and emulsified water.
  • Air/Vapor Removal: Patented process eliminates entrained air/vapor that damage injection systems and reduce power and efficiency.
  • 2 Micron Absolute Filtration (Microglass): Removes debris smaller than OEM filters can catch.
  • Mass Flow Return (MFR): Continuously polishes your diesel by returning unused fuel through the filters so your tank always holds clean, conditioned fuel.

Key Benefits

  • Improves Reliability: WILL TRIPLE the injection system life.
  • Maximized Horsepower: Stronger throttle response, improved fuel atomization, restored injection timing, and a more balanced engine.
  • Optimized MPG: More efficient and complete combustion.
  • Peace of Mind: The Extreme Water Separator acts as a fail-safe during severe fuel contamination. If it reaches capacity it acts as a dam and shuts down fuel flow, preventing costly repairs and downtime.
  • Cold Weather Confidence: Reliable starts and operation in harsh climates, especially when paired with the appropriate FASS Fuel Heater.
  • Proven Reliability: Less than a 0.5% failure rate.
  • Cleaner Operation: Improved fuel quality and combustion reduces DPF regens and soot output.
  • Improves Fuel Lubricity: Increases lubricity by at least 10% by removing entrained air/vapor.
  • Lower Cost of Ownership: Reduced maintenance and fewer injection-system repairs.
  • Consistent Engine Performance: Reduces "hot fuel" effects and delivers true engine balancing with a smoother, quieter idle.
  • Easier Startups: Dependable starts, including extreme cold weather operation.
  • Reduced Emissions and Temps: Reduces regenerations, soot, EGTs, and water and oil temperatures and consumption.

Key Features

  • Fuel Flow: 100 GPH, supports stock and modified 6.6L Duramax engines up to 600 HP.
  • 2 Micron Absolute Filtration: Captures finer debris than OEM filters.
  • Water Removal: Removes over 99% of free and emulsified water from fuel (third-party verified).
  • Patented Air/Vapor Removal Process
  • Fuel Lubricity: Increases lubricity by at least 10%.
  • Injector Life: WILL TRIPLE the life of fuel injection components.
  • Motor Life: Rated for over 1,000,000 miles.
