- Titanium Signature Series Plus: This next-generation system features premium upgrades like ORB (O-Ring Boss) fittings, black anodized 6061 aluminum fittings, and black fuel lines for a sleek and ultra-clean installation.
- FASS Silencing Technology (FST): By using precise radius cuts, tighter tolerances, and a military-spec coating, this system is engineered to be the quietest aftermarket fuel pump on the market.
- 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 continuously "polishes" your fuel. By returning filtered, unused fuel to the tank, it guarantees that your engine always receives the freshest, cleanest fuel possible.
- Bolt-On Installation: The included brackets mount directly to your factory bed bolts, making installation quick and easy with no drilling or welding required.
- Extra Deep Sump: The single-bolt sump kit draws fuel from the very bottom of the tank, providing a constant and reliable fuel supply, even at low fuel levels.

A high-performance diesel engine demands the cleanest fuel possible, and the FASS NDTSPC10165G No-Drop Kit Titanium Series Plus 165GPH Fuel System & Sump delivers just that for your Chevy/GMC 6.6L Duramax LB7/LLY/LBZ/LMM. This isn’t just a fuel pump; it’s a complete filtration and fuel delivery system engineered for the most reliable performance on the market. Rated at a robust 165 gallons per hour, it’s designed for trucks with 600-900 HP. It provides a patented process to remove air and vapor, a built-in water separator, and an advanced 2-micron filtration rating. This level of purity protects your costly fuel injection system, extending the life of your pump and injectors while improving cold-weather starts, efficiency, and idle quality. With the included FASS Fuel Sump, you can install this system without the hassle of dropping your fuel tank, providing an affordable and all-in-one solution.
