Peace of Mind, Efficiency, Power
- Supports Stock & Modified Duramax: Plenty of fuel for stock and modified GM/Chevy trucks.
- Injector Protection: Triples the life of injectors and injection pump.
- FASS Filtration: Optimizes combustion, restores horsepower, and maximizes MPG (results vary).
- Limited Lifetime Warranty: Coverage with product registration.
Advanced Filtration Technology
FASS doesn’t just move fuel — we filter it better than anyone:
- Water Separation: Third‑party proven to remove over 99% of water.
- Air/Vapor Removal: Eliminates entrained air and vapor that damage injection systems.
- 2‑Micron Absolute Filtration (Microglass): Removes debris smaller than OEM filters.
- Mass Flow Return (MFR): Continuously polishes fuel by recirculating unused fuel through the filters.
Key Benefits
- Improved Reliability: Extends injection system life up to 3×.
- Maximized Horsepower: Improved throttle response and balanced injection timing.
- Optimized MPG: More complete combustion (results vary).
- Peace of Mind: Extreme Water Separator prevents costly fuel contamination damage.
- Extreme Cold Weather Confidence: Reliable starts in harsh climates when paired with a FASS Fuel Heater.
- Proven Reliability: Less than a 0.5% failure rate.
- Cleaner Operation: Reduced DPF regens and soot output.
- Improves Fuel Lubricity: Increases lubricity by at least 10%.
