FASS Titanium Signature Series 165GPH Fuel System for GMC/Chevrolet 1992-2000 Turbo Diesel 6.5L (TSC08165G)

Product Manuals

If you drive a 1992-2000 GMC/Chevrolet with the 6.5L Turbo 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 Fuel System, to outlast and outperform anything else on the market. This system is designed to provide the purest possible fuel to your 6.5L Turbo Diesel and built to outlast it.

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 6.5L Turbo Diesel: 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 soot output.
• Improves Fuel Lubricity: Increases lubricity by at least 10% by removing entrained air/vapor.
