FASS (Fuel Air Separation System) Fuel Systems are advanced diesel fuel systems designed to improve diesel engine performance and efficiency by removing contaminants and air from the fuel. These systems are popular in the trucking, agriculture, and construction industries due to their ability to increase fuel injector life, improve fuel economy, and boost engine power. Key benefits and features include:

1. Air Separation: FASS systems remove air and vapor trapped in the diesel fuel, which can cause poor combustion, engine wear, and reduced fuel efficiency.
2. Filtration: High-quality filters remove water, particulates, and contaminants, helping to protect injectors and fuel pumps from damage.
3. Fuel Heating Options: Many FASS systems include fuel heating features, which prevent gelling in colder climates, allowing diesel engines to operate more reliably in cold conditions.
4. Enhanced Performance: With a cleaner and more consistent fuel supply, engines can perform more efficiently, often with increased horsepower and torque.

FASS offers systems compatible with various makes and models, allowing for customizations depending on specific needs (e.g., heavy-duty versus everyday diesel use). Their systems are often valued for extending fuel system life, lowering maintenance costs, and improving overall fuel economy.
