When driving a 2019–2024 Ram with the 6.7L Cummins diesel engine, ensuring pristine fuel quality is essential. Modern common-rail systems operate under extremely high pressure, and even tiny contaminants or air can damage injectors and pumps.
Upgrading your filter and fuel system protects performance, extends component life, and improves reliability.
Why Upgrading Makes a Difference
- Air & Vapor Removal — Air entrained in fuel reduces pressure consistency, leads to cavitation, and damages injection components over time.
- Water Separation — Diesel fuel often carries free water, which leads to corrosion, injector damage, and system wear.
- Fine Particle Filtration — Stock filters often miss micro-contaminants. A quality system filters down to
2 microns to protect injectors and the CP4 pump.
Installing a superior fuel system like those offered by FASS helps:
- Increase the lifespan of injectors and the fuel pump (up to 3× longer)
- Restore and maintain horsepower and torque
- Sharpen throttle response and provide smoother performance
- Improve fuel economy under demanding conditions like towing or hauling
FASS Fuel System Options for the 2019–2024 6.7L Cummins
Drop-In Series (Stock to Mildly Modified Use)
- Maintains the OEM in-tank lift pump
- Upgrades filtration to 2 microns with advanced water and air separation
- Straightforward installation using existing lines
- Ideal for everyday driving, moderate towing, and light performance upgrades
Titanium Signature Series & PLUS (High Flow/High Demands)
- Full system upgrade including a higher capacity lift pump
- Multiple flow rates to match power levels and modifications:
• ~140 GPH — stock to mild builds
• ~220 GPH — moderate to heavy towing or upgraded engines
• ~240–260 GPH — high horsepower or performance turbo setups - “No-Drop” option available to avoid dropping the fuel tank
- PLUS versions come with upgraded fittings and fuel lines for strong durability and appearance
Choosing the Right System
- Evaluate how you use the truck (daily driving, towing, extreme performance)
- Assess whether the OEM pump is still reliable
- Determine the horsepower and fuel demand for your build
- Decide if you want a simple “bolt-in” filter upgrade (Drop-In) or a complete system overhaul (Titanium Series)
Takeaway
For 2019–2024 Cummins owners, upgrading your fuel filtration with FASS is more than just insurance—it’s unlocking cleaner fuel, more consistent power, and lasting component protection.
Whether you go with
Drop-In for simplicity or the Titanium Series for maximum flow and durability, choosing the right filter system pays off in reliability and performance.
