- FASS Silencing Technology (FST): This exclusive technology uses precise radius cuts, tighter tolerances, and a military-grade coating to deliver the quietest operation possible without sacrificing flow.
- Performance Radius Cuts (PRC): Unlike competitors who use restrictive, sharp-angled fittings, FASS uses an advanced machining technique to create smooth-flowing cuts within the pump housing. This prevents the reintroduction of air and vapor and eliminates stagnant fuel pockets for optimal flow.
- Mass Flow Return (MFR): This patented technology continuously "polishes" your fuel. By returning filtered, unused fuel to the tank, it guarantees that your engine is always running on the freshest, cleanest fuel possible.
- Bolt-On Brackets: Installation is straightforward. The included durable, machined steel brackets bolt directly to your factory bed bolts, so no drilling or welding is required.
- Extra Deep Sump: The included single-bolt sump kit provides a constant and reliable fuel supply from the bottom of the tank, preventing fuel starvation and ensuring consistent performance, even when fuel levels are low.

Your Dodge Ram is a powerful machine, and its performance depends on clean, pure fuel. That's why the FASS NDTSD08100G No-Drop Kit Titanium Series 100GPH Fuel System & Sump with Whisper Technology is engineered to be the most reliable and highest-performing aftermarket filtration system on the market for your 1998.5-2004.5 Dodge Ram 5.9L Diesel. Rated at 100 gallons per hour, this system is ideal for engines ranging from stock to 600 HP. It offers a patented process that removes air and vapor, a built-in water separator, and an exceptional 3-micron filtration rating. This advanced cleaning process protects your expensive injection pump and injectors, extending their lifespan and ensuring your truck runs at its best. What's more, the included FASS Fuel Sump makes installation a breeze by eliminating the need to drop your fuel tank entirely, providing a complete and affordable solution.
