- FASS Whisper Technology (FWT): Developed to reduce noise, this technology uses radius cuts, tight tolerances on all gears, and a military-grade coating to create the quietest fuel system on the market.
- Performance Radius Cuts (PRC): This advanced machining technique creates a smooth fuel path within the pump housing, preventing the reintroduction of air and vapor and eliminating stagnant fuel pockets that can limit flow.
- Mass Flow Return (MFR) Technology: This process continuously "polishes" your fuel by maintaining positive pressure and returning unused fuel to the tank after it has been thoroughly filtered. This ensures your engine always receives the cleanest, freshest fuel possible.
- Bolt-On Bracket Mounts: Installation is a breeze with durable, machined steel brackets that utilize your factory bed bolts, eliminating the need for drilling or welding.
- Advanced Filtration: This system offers an enhanced 2-micron filtration rating and a built-in water separation filter, providing superior protection for your fuel injection system and extending the life of your injectors.
