FASS TSC15180F140G – Titanium Signature Series 140GPH Fuel System

Mount the FASS TSC15180F140G Titanium Signature Series 140GPH Fuel System on your 2020–2023 GM Silverado/Sierra 2500HD/3500HD 6.6L L5P Duramax (Stock to Moderate – requires tuning) and get superior fuel delivery and filtration. Engineered to be the most reliable aftermarket fuel/filtration system in the industry, this American-made system is rated at 140 GPH—supporting stock and upgraded fueling systems with ease.

Advanced Protection for Your Fuel System:
With a 2-micron filtration rating, built-in water separator, and patented air/vapor removal process, the Titanium Signature Series helps eliminate the fuel-related issues that often lead to injector failures. This not only extends injector and pump life but also ensures consistent, clean fuel delivery under all driving conditions.

FASS Innovations:

  • Whisper Technology (FWT): Developed over 2.5 years of testing, FWT drastically reduces pump noise while improving fuel flow rates, giving you quiet operation without sacrificing performance.
  • Performance Radius Cuts (PRC): Exclusive machining process creates smooth flow paths inside the housing, reducing restrictions and preventing air/vapor reintroduction into the fuel.
  • Mass Flow Return (MFR): Continuously “polishes” fuel by filtering and recirculating unused fuel back into the tank, removing contaminants and ensuring your engine always receives the cleanest possible diesel.
  • Bolt-On Bracket Mounts: Simplified installation using your truck’s factory bed bolts—no welding or drilling required. Heavy-duty steel brackets provide long-term durability and support.
