About FASS

FASS stands for Fuel Air Separation System. The company got its start in 2003 and is based in Marthasville, Missouri. A FASS system pulls air and vapor out of the fuel and sends it back to the tank, and it filters water and dirt out before the fuel reaches the injection system. Cleaner, air-free fuel is easier on injectors and the high-pressure pump.

What we carry

We stock 75 FASS part numbers for Cummins, Duramax, Powerstroke and EcoDiesel pickups.

  • Titanium Signature Series fuel systems, the main pickup lift pump and filtration kit
  • Titanium Signature Series PLUS kits
  • No-Drop and No-Drop PLUS kits, named because the fuel tank stays in the truck during install
  • Drop-In Series bolt-on filtration
  • Replacement filters, including the PF3001XL extended-length particulate filter
