- FASS Silencing Technology (FST): This exclusive technology uses precision machining and a military-grade coating to create the quietest fuel air separation system on the market.
- Performance Radius Cuts (PRC): Unlike competitors who use restrictive, sharp-angled fittings, FASS uses advanced machining to create smooth-flowing cuts. This prevents air reintroduction and ensures optimal fuel flow.
- Mass Flow Return (MFR): This patented technology continuously polishes your fuel by returning filtered, unused fuel to the tank. This guarantees 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.
- Extra Deep Sump: The single-bolt sump kit draws fuel from the very bottom of the tank, providing a constant and reliable fuel supply and preventing starvation, even at low fuel levels.

You know your truck’s performance depends on clean fuel. The FASS NDTSD08165G No-Drop Kit Titanium Series 165GPH Fuel System & Sump with Whisper Technology is engineered to be the most reliable and high-performing aftermarket filtration system for your Dodge Ram 5.9L Diesel. Rated at an impressive 165 gallons per hour, this system is ideal for engines with 600-900 HP. It offers advanced 3-micron filtration, a built-in water separator, and a patented air/vapor removal process. This level of purity protects your expensive fuel injection system and extends the life of your injection pump and injectors. And with the included FASS Fuel Sump, you can install this system without the hassle of dropping your fuel tank, saving you time and money compared to buying the components separately.
