Download Product Manual

Upgrade the fuel-delivery and filtration system on your 1992–2000 GMC or Chevrolet 6.5L Turbo Diesel with the FASS Titanium Signature Series PLUS Fuel System. Designed for stock and modified applications, this system supplies clean, air-free diesel fuel to help protect the injection system and support dependable engine performance.

The Titanium Signature Series PLUS removes water, debris, air, and vapor before fuel reaches the engine. Supplying properly filtered and conditioned diesel can help improve combustion, throttle response, fuel-system reliability, fuel efficiency, and cold-weather operation.

This PLUS system also includes an upgraded black-anodized aluminum motor heat sink. By helping reduce internal motor temperature, the heat sink supports long motor life while giving the system a clean, finished appearance.

Dependable Fuel Delivery and Injection-System Protection

• Supports Stock and Modified Engines: Available flow configurations provide dependable fuel delivery for factory and performance-built 6.5L Turbo Diesel applications.
• Injection-System Protection: Cleaner diesel fuel helps reduce wear on the injectors, injection pump, and other fuel-system components.
• Improved Combustion: Removing contaminants, water, air, and vapor supports more complete combustion and consistent engine operation.
• Performance Support: Properly conditioned fuel can help improve throttle response, fuel atomization, horsepower, and overall engine balance.
• Limited Lifetime Warranty: Warranty coverage is available after the FASS system is properly registered.

Advanced FASS Filtration Technology

FASS systems do more than transfer fuel. They continuously filter and condition diesel before it reaches the injection system.

• Water Separation: Third-party testing verifies removal of more than 99% of water from diesel fuel.
• Air and Vapor Removal: The patented FASS process removes entrained air and vapor that may reduce efficiency and contribute to injection-system wear.
• 2-Micron Absolute Microglass Filtration: Captures extremely fine contaminants that may pass through standard OEM filters.
• Mass Flow Return: Unused fuel is continuously circulated back through the filtration system, helping keep the tank supply clean and conditioned.

Key Benefits

• Improved Reliability: Cleaner diesel fuel helps extend the service life of injectors and other injection-system components.
• Stronger Engine Response: Consistent fuel delivery supports improved throttle response, fuel atomization, and injection timing.
• Fuel-Economy Potential: More efficient combustion may contribute to improved fuel economy. Results vary by vehicle, condition, and driving habits.
• Added Contamination Protection: The Extreme Water Separator provides an additional safeguard against severely contaminated fuel.
• Cold-Weather Confidence: Supports dependable starting and operation in low temperatures, especially when paired with a compatible FASS Fuel Heater.
• Proven Durability: FASS reports a fuel-system failure rate below 0.5%.
• Cleaner Engine Operation: Improved fuel quality and combustion may help reduce soot output.
• Improved Fuel Lubricity: The FASS conditioning process can increase diesel-fuel lubricity by at least 10%.
