- FASS Silencing Technology (FST): Experience an incredibly quiet operation. This exclusive technology uses precise radius cuts and a military-grade coating to minimize pump noise without compromising performance.
- Performance Radius Cuts (PRC): FASS is the only brand to use this advanced machining technique. PRC creates smooth-flowing cuts within the housing to prevent air reintroduction and ensure maximum fuel flow, unlike competitors' restrictive 90-degree fittings.
- Mass Flow Return (MFR): This patented technology constantly "polishes" your fuel. By returning filtered, unused fuel to the tank, it ensures your engine always receives the freshest, cleanest fuel possible.
- Bolt-On Brackets: The included brackets mount directly to your factory bed bolts, making installation quick and easy with no drilling or welding required.

For high-horsepower, custom-tuned 2017-2019 GM 6.6L Duramax L5P trucks, a reliable fuel system isn't just an option—it’s a necessity. The FASS TS C13 220G Titanium Signature Series 220GPH Fuel System with Whisper Technology is engineered to be the most reliable and highest-performing aftermarket filtration system on the market. Rated at a robust 220 gallons per hour, it's designed for moderate to extreme engines pushing 500 to 900 HP. This advanced system protects your Duramax fuel system by removing air, vapor, water, and debris down to an impressive 3 microns. This keeps your injectors and other components in top condition, ensuring your truck runs at its best.
