When maximum fuel system protection, reliability, and uptime matter, the FASS Ultimate Industrial Fuel System Upgrade combines two of our most advanced heavy-duty fuel system technologies into one complete package.
The Industrial Series PLUS provides dependable fuel delivery, Extreme water separation, Continuous Fuel Polishing, 2-micron absolute filtration, and FASS air/vapor separation technology. The Drop-In Series HD System adds an additional high-capacity 2-micron absolute filtration and air-separation stage, providing another level of protection before fuel reaches your diesel injection system.
Together, these systems are engineered for demanding diesel applications where fuel quality, injector protection, and dependable operation are critical.
Ultimate Fuel System Protection
This package combines fuel delivery, water separation, particulate filtration, air/vapor removal, and continuous fuel conditioning into one comprehensive diesel fuel system solution.
- Extreme Water Separation: Removes over 99% of water from diesel fuel through the Industrial Series Extreme Water Separator.
- Dual 2-Micron Absolute Filtration: Both systems utilize high-efficiency synthetic microglass particulate filtration capable of capturing contaminants smaller than OEM filters.
- Advanced Air & Vapor Removal: FASS technology removes entrained air and fuel vapor that can contribute to poor combustion, injector wear, and inconsistent engine performance.
- Continuous Fuel Polishing (CFP): Continuously recirculates fuel through the Extreme Water Separator before it is supplied to the injection system.
- Additional Filtration Protection: The Drop-In Series provides another high-capacity filtration and air-separation stage for demanding commercial and industrial applications.
- Injector & Injection Pump Protection: Cleaner, water-free, air-free fuel helps dramatically extend the life of expensive fuel injection components.
Peace of Mind. Efficiency. Power.
Injector Protection
FASS fuel conditioning technology will TRIPLE the life of your fuel injection system by reducing damaging water, particulates, entrained air, and vapor before they reach the injection system.
Maximized Horsepower
Improved fuel quality promotes better fuel atomization, more consistent injection timing, improved throttle response, and a smoother, more balanced engine.
Optimized MPG
Removing contaminants and entrained air helps promote more efficient and complete combustion, helping maximize fuel economy. Results will vary by application and operating conditions.
Cleaner Operation
Improved fuel quality and combustion can help reduce soot production and DPF regeneration frequency in emissions-equipped diesel engines.
Improved Fuel Lubricity
FASS fuel conditioning technology can improve diesel fuel lubricity by at least 10%, helping protect high-pressure fuel system components.
Industrial Series PLUS Technology
The Industrial Series PLUS serves as the foundation of this Ultimate package, delivering conditioned fuel to your diesel engine while continuously protecting the fuel supply.
Extreme Water Separation
Third-party verified technology removes over 99% of water from diesel fuel, helping protect sensitive injection components from corrosion and premature wear.
Continuous Fuel Polishing
FASS Continuous Fuel Polishing (CFP) technology repeatedly circulates fuel through the Extreme Water Separator before the fuel is delivered to the engine.
Rather than simply filtering the fuel once, CFP continually conditions the fuel supply to help ensure the engine receives the cleanest diesel fuel possible.
2-Micron Absolute Microglass Filtration
High-efficiency synthetic microglass filtration removes extremely fine debris that can pass through many factory filtration systems.
Patented Air/Vapor Removal
FASS technology removes entrained air and fuel vapor that can interfere with fuel delivery, injection timing, fuel atomization, and overall combustion efficiency.
Industrial Series PLUS Features

Whisper Technology
Engineered to provide extremely quiet fuel pump operation while maintaining dependable fuel delivery.
Performance Radius Cuts (PRC)
Internal fuel passages utilize smooth radius transitions instead of sharp restrictions to promote more efficient fuel flow throughout the system.
Aluminum Motor Heat Sink
A black anodized aluminum motor heat sink helps lower internal motor temperatures by up to 20°F, helping extend the life of the proven FASS million-mile motor while providing an upgraded finished appearance.
Drop-In Series HD Additional Protection
The FASS Drop-In Series Universal HD Fuel Air Separation System adds another extremely flexible filtration and air-separation stage to the Ultimate package.
Designed for universal diesel applications, the Drop-In Series can be incorporated into a wide variety of fuel system configurations and can operate alongside OEM filtration or as a final filtration stage where appropriate.
Drop-In Series Features
