The Best Fuel Filter for Your 2017-2025 6.7L Powerstroke
If you own a 2017–2025 Ford F-250, F-350, or F-450 with the 6.7L Powerstroke, feeding it the cleanest fuel possible is essential.
While the factory filtration is good, modern high-pressure fuel systems are very sensitive to contamination. Upgrading your fuel filtration with a FASS system provides the protection and performance your truck deserves.
Why You Should Upgrade Your Fuel System
Stock filtration may filter out many large particles, but it falls short in three major areas:
- Entrained air / vapor – Blueprints for injector issues and unpredictable fuel delivery.
- Water intrusion – Even small amounts of water can lead to corrosion or pump damage.
- Fine debris – Old filters often allow particles small enough to damage injectors or reduce pump life.
Upgrading your fuel system greatly reduces these threats. With cleaner fuel, you’ll get:
- 3× the injection system life by minimizing wear on injectors and the high-pressure fuel pump.
- Enhanced performance: stronger, more consistent power, sharper throttle response, and potentially better fuel economy.
- Peace of mind – Knowing your truck is protected from fuel-related failures, especially when it’s your workhorse.
Best Options for Your Setup
Here’s what FASS offers for 2017–2025 6.7L Powerstroke owners, depending on use:
For Daily Driving or Light Modifications:
FASS Drop-In Series (Part No.
DIFSFRD1001)
- 2-micron filtration — much finer than stock, capturing smaller particles.
- Removes over 99% of water and clears air/vapor from fuel.
- Easy to install — uses factory mount location and lines, works with the original in-tank lift pump.
- Ideal for stock trucks, light towing, general use.
For Higher Mileage, Towing, or Performance Builds
FASS Titanium Signature Series & Signature Series PLUS
- Complete fuel system upgrade with a high-volume lift pump.
- Multiple flow rate options to match horsepower needs:
• ~140 GPH — stock to moderately modified (up to ~700 HP)
• ~220 GPH — heavier modified builds (700–900 HP)
• ~240 GPH — competition/extreme HP builds (900-1200 HP) - PLUS models include upgraded fittings and fuel lines for improved durability and appearance.
- “No-Drop” option available (fuel sump kit) to avoid dropping the tank.
What to Consider When Choosing
- How you use the truck (daily drive, towing, performance)
- Whether the factory pump is still in good condition
- Whether you want a “bolt-in” solution (Drop-In) or full system upgrade (Titanium Series)
- Anticipated horsepower, towing load, and expected life of components
Final Word
For your 2017-2025 6.7L Powerstroke, investing in a quality filtration system from FASS isn’t just about protection—it’s about unlocking dependable power, fuel economy, and durability.
Whether you choose the Drop-In Series for simplicity or the Titanium Signature line for maximum performance, the right filter makes all the difference.
