FASS TSC13180F140G Titanium Signature Series 140GPH Fuel System

The FASS TSC13180F140G Titanium Signature Series 140GPH Fuel System is the premium fuel and filtration upgrade for your 2017–2019 GM Silverado/Sierra 2500HD/3500HD 6.6L L5P Duramax (Stock to Moderate – Requires Tuning). Engineered for superior reliability and protection, this system delivers advanced fuel filtration and whisper-quiet operation to safeguard your injection pump and injectors while extending service life.

Featuring a 2-micron filtration rating, built-in water separation, and FASS’ patented air/vapor removal process, this system ensures only the cleanest fuel reaches your engine. By eliminating harmful contaminants, it enhances performance, reliability, and fuel system longevity.

Whisper Technology (FWT): Developed over 2.5 years, this exclusive technology drastically reduces operating noise while maintaining higher flow rates, providing one of the quietest diesel fuel systems on the market.

Performance Radius Cuts (PRC): Advanced machining creates smooth internal fuel passages within the aluminum housing, preventing restrictions, eliminating sharp 90° corners, and reducing the chance of air or vapor reintroduction. Unlike competitor systems that use restrictive fittings, PRC guarantees efficient fuel flow.

Mass Flow Return (MFR) Technology: Fuel is continually “polished” by maintaining positive pressure to the engine supply while returning unused, filtered fuel back to the tank. This process removes air, vapor, water, and debris for consistently clean fuel delivery, ensuring optimal performance even in cold weather.

Easy Bolt-On Installation: The included bolt-on bracket mounts directly to the factory bed bolt, eliminating the need for drilling or welding. Brackets are constructed from machined steel for exceptional durability and support.
