- FASS Silencing Technology (FST): Experience a quiet and smooth operation. This technology uses precise radius cuts, tighter tolerances, and a military-spec coating to reduce 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 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 Brackets: Installation is straightforward and simple. 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 draws fuel from the very bottom of the tank, providing a constant and reliable fuel supply, even in low-fuel situations.
