FASS Titanium Signature Series 290GPH Fuel System for Dodge/RAM 1998.5-2004 Cummins 5.9L

If you drive a 1998.5–2004 Dodge/RAM with the Cummins diesel engine, upgrading your fuel filtration and delivery will triple the life of the injection system, increase MPG and power, and provide exceptional extreme cold weather operation.

That’s exactly why we engineered the Titanium Signature Series Fuel System—to outlast and outperform anything else on the market. This system is designed to provide the purest possible fuel to your Cummins and built to outlast it.

Peace of Mind, Efficiency, Power

Supports Stock & Modified Cummins: Plenty of fuel for stock and modified Dodge/RAM applications.

Injector Protection: Will triple the life of your injectors and injection pump.

FASS Filtration: Optimizes combustion, restores horsepower, and maximizes MPG (results vary).

Limited Lifetime Warranty: Register your FASS system and you’re covered.

Advanced Filtration Technology

FASS doesn’t just move fuel—we filter it better than anyone.

Water Separation: Third‑party proven to eliminate over 99% of water.

Air/Vapor Removal: Eliminates entrained air and vapor that damage injection systems and reduce power and efficiency.

2‑Micron Absolute Filtration (Microglass): Removes debris smaller than OEM filters can catch.

Mass Flow Return (MFR): Continuously polishes your diesel by returning unused fuel through the filters so your tank always holds clean, conditioned fuel.

Key Benefits

Maximized Horsepower: Stronger throttle response, improved fuel atomization, restored injection timing, and a more balanced engine.

Optimized MPG: More efficient and complete combustion (results vary).

Peace of Mind: Extreme Water Separator acts as a fail‑safe during severe fuel contamination, preventing costly repairs and downtime.
