- FASS Silencing Technology (FST): Utilizing "Whisper Technology," this system incorporates radius cuts and military-spec coatings to significantly reduce operational noise, making it the quietest fuel-air separation system on the market.
- Performance Radius Cuts (PRC): Unlike competitors that use restrictive 90-degree fittings, FASS uses precision-machined smooth transitions to prevent fuel stagnation and the reintroduction of air into the lines.
- Mass Flow Return (MFR): This technology continuously "polishes" your fuel by circulating it through the filtration process and returning unused, cleaned fuel to the tank, ensuring a constant supply of the highest quality diesel.
- Superior Filtration: Features a 3-micron filtration rating and built-in water separation, effectively eliminating contaminants that lead to injector failure and rough idling.
- No-Drop Installation: The included single-bolt fuel tank sump allows for a complete installation without the labor-intensive process of removing the fuel tank.
- Durable Mounting: Machined steel bolt-on brackets utilize existing factory bed bolts, providing a secure, drill-free attachment to the frame.
- Optimized Performance: Designed to improve cold weather starts and increase overall engine efficiency by delivering a consistent, debris-free fuel stream.
Optimizing the performance and longevity of your 2020–2023 L5P Duramax requires a fuel delivery system that addresses the inherent weaknesses of factory filtration. The FASS NDTSC15180F140G No-Drop Kit Titanium Series 140GPH Fuel System and Sump is engineered specifically for trucks ranging from stock to moderately tuned configurations. By integrating advanced fuel-air separation technology, this system ensures that your fuel injection components are shielded from the primary causes of premature wear: entrained air, water, and debris. This kit represents a comprehensive solution for owners looking to safeguard their investment while supporting future fueling upgrades through a robust 140 gallons per hour flow rate.
