Videos (1)
Upgrade your 6.7L Powerstroke's defense against dirty fuel with the FASS DIFSFRD1001 Drop-In Series Fuel Filter System. This system safeguards your Ford truck's fuel injection system from the damaging effects of contaminated fuel.
- Superior Filtration: Removes over 99% of water, air, and particles as tiny as 2 microns, extending the lifespan of your fuel injection system.
- Enhanced Performance: Cleaner fuel can potentially improve your MPG (results may vary), restore horsepower, and sharpen throttle response.
- Unmatched Water Removal: The innovative Extreme Water Separator (XWS) boasts industry-leading efficiency, eliminating over 99% of water from your fuel. If overloaded, the XWS acts as a failsafe, shutting down your truck to prevent fuel system damage.
- Simplified Installation: This true plug-and-play system eliminates the need for cutting, wiring, or additional modifications.
FASS Drop-In Technology:
- Seamless Integration: Designed for effortless installation while delivering filtration on par with FASS's premium Titanium Signature Series and Industrial Series systems.
- Performance Radius Cuts (PRC): This innovative technology creates smooth-flowing fuel paths within the system. This prevents air and vapor from re-entering the fuel and avoids the formation of eddy currents.
Key Features:
- Traps particles as small as 2 microns
- Maintains the stock in-tank lift pump
- 100% drop-in design for a hassle-free installation
- Extends the life of fuel injection system components
- Combines filtration with efficient air separation
- Preserves the water-in-fuel sensor functionality
- Offers optional electric heater for improved cold-weather performance
- Internal air separation passages eliminate entrained air and vapor
- Boosts fuel lubricity by up to 10% by removing air and vapor
- Utilizes Extreme Water Separator technology for superior water removal (over 99%)
Note:
The Drop-In Series Fass for the Ford 6.7L Powerstroke was designed to mount in the factory water separator location and may not work with aftermarket fuel tanks that have greater fuel capacity than the stock fuel tank. You must verify that you have adequate space to mount the drop-in series fass system if you have an aftermarket fuel tank.
This filter system fits Crew Cab Short Bed, and Crew Cab Long Bed trucks.
