    The FASS Titanium Signature Series Plus 240GPH Fuel System represents the pinnacle of diesel engineering for the 2020-2023 L5P Duramax. Designed specifically for highly modified builds ranging from 900 to 1200 HP, this system is an essential upgrade for owners who demand peak reliability and performance. By replacing the stock configuration with a complete high-volume system, you ensure that your engine never starves for fuel under load. This "Plus" evolution introduces a sophisticated aesthetic and leak-resistant design, utilizing O-Ring Boss (ORB) fittings and black anodized 6061 aluminum components. Beyond mere volume, this system serves as a guardian for your expensive injection components, utilizing a multi-stage process to scrub the fuel of the three primary enemies of diesel performance: air, vapor, and water.

    • Extreme Fuel Delivery: Provides a massive 240 gallons per hour at 70-75 PSI, supporting high-output applications while maintaining a steady fuel volume.
    • Advanced 2-Micron Filtration: Offers superior protection against microscopic debris, significantly extending the service life of your injectors and high-pressure fuel pump.
    • FASS Whisper Technology (FWT): Utilizes military-spec coatings and precision-radius gear tolerances to deliver the quietest operation of any air separation system currently on the market.
    • Performance Radius Cuts (PRC): Employs smooth, machined internal pathways to eliminate the turbulence and "stagnant pockets" common in inferior 90-degree fittings, preventing the reintroduction of air into the fuel stream.
    • Mass Flow Return (MFR): Continually polishes your fuel by cycling unused, filtered diesel back to the tank, ensuring the fuel entering your engine is always at optimal pressure and purity.
    • Simplified Installation: Features heavy-duty, bolt-on steel brackets that utilize factory bed bolts, eliminating the need for drilling or welding on your truck's frame.
    • Reliability Enhancements: Improves cold weather starting, smooths out engine idle, and includes 1/2-inch fuel lines to maximize flow efficiency.

    Investing in the Titanium Signature Series Plus is about more than just hitting horsepower targets; it is about the long-term health of your Duramax L5P. The integration of a built-in water separator and the patented air removal process ensures that only pure, liquid diesel reaches your combustion chamber, which leads to improved fuel mileage and increased mechanical efficiency. Every component, from the 30,000-mile filter life expectancy to the limited lifetime warranty, is designed to provide peace of mind for the serious enthusiast. Whether you are building a dedicated tow rig or a high-performance street machine, this system provides the consistent, clean fuel delivery necessary to protect your investment and maximize your truck's true potential.
