- FASS Silencing Technology (FST): Experience an incredibly quiet operation. This technology uses precise radius cuts and a military-spec coating on the aluminum base to minimize noise.
- Performance Radius Cuts (PRC): FASS is the only brand to use this advanced machining technique, which creates smooth-flowing cuts to prevent the reintroduction of air and vapor while ensuring maximum fuel flow.
- Mass Flow Return (MFR): This technology constantly "polishes" your fuel. By keeping a positive pressure on the fuel and returning it to the tank after filtration, it ensures you're always running on the cleanest, freshest fuel possible.
- Bolt-On Brackets: Installation is streamlined with durable, machined steel brackets that attach directly to your factory bed bolts, so there's no drilling or welding required.
- Extra Deep Sump: The included single-bolt sump kit provides a consistent fuel supply from the bottom of the tank, preventing fuel starvation and increasing reliability, even when your tank is low.

Your truck’s fuel system is a complex and expensive piece of machinery, and nothing protects it better than a high-quality filtration system. The FASS NDTSC12100G No-Drop Kit Titanium Series 100GPH Fuel System & Sump is the pinnacle of aftermarket filtration for your 2015-2016 GM 6.6L Duramax. Designed for stock to 600HP applications, this system is engineered to be the most reliable and highest-performing on the market. It offers a sophisticated 3-micron filtration rating and a patented process that removes air and vapor from your fuel. The result? A protected fuel injection system with a longer lifespan, improved efficiency, and smoother idle. What's more, the included FASS Fuel Sump makes installation a breeze by eliminating the need to drop your fuel tank, providing an all-in-one solution that's simpler and more affordable than buying the components separately.
