When most people think of FASS Diesel Fuel Systems, they picture powerful Cummins, Duramax, or Powerstroke pickup trucks—and for good reason. FASS has become a trusted name in the diesel performance world, known for delivering cleaner fuel, consistent pressure, and long-term protection for injection systems.
But what many don’t realize is that FASS systems are available for a much wider range of diesel-powered equipment, including farm machinery, construction equipment, commercial trucks, generators, and even custom diesel projects. Whether you rely on your diesel for work, play, or production, FASS has a solution to keep it running stronger and longer.
Clean, Consistent Fuel Delivery for Any Diesel Application
No matter the vehicle or equipment type, every diesel engine faces the same fundamental challenges:
- Air and vapor in the fuel can cause pressure fluctuations, hard starts, lost horsepower, reduced MPG, and cavitation damage.
- Water contamination leads to corrosion and injector wear—which can be catastrophic in extreme cases.
- Poor filtration allows debris to harm sensitive injection components.
FASS Diesel Fuel Systems are engineered to tackle these issues head-on by removing air/vapor, separating water, and filtering down to 2 microns absolute—ensuring your injection system gets only clean, consistent fuel. This translates to better performance, optimized MPG, and 3x (or more) injection system life.
More Than Just Pickup Trucks
While many customers know us for popular pickup platforms like the Ram 6.7L Cummins, Ford 6.7L Powerstroke, and GM 6.6L Duramax, FASS systems are also an excellent upgrade for:
- Farm Equipment – Tractors, combines, sprayers, and stationary diesel engines benefit from cleaner fuel, especially in dusty or high-use environments.
- Construction Equipment – Skid steers, excavators, dozers, and generators can see reduced downtime and longer injector life.
- Medium- and Heavy-Duty Trucks – Including delivery trucks, vocational vehicles, and older commercial diesel rigs that can benefit from modern filtration and lift pump technology.
- Custom Diesel Projects – Hot rods, marine applications, off-road builds, or retrofitted work trucks can be equipped with universal FASS setups for stable fuel supply.
