FASS Filters shipped right to your door!
Routine filter changes are key to keeping any diesel pickup running strong, and FASS makes that job simple. Every FASS Fuel System is designed with easy fuel filter changes in mind—no special tools, no complicated disassembly.
Whether you drive a class 8 truck, or a pickup with a Cummins, Duramax, or Powerstroke, replacing your
FASS Filters
takes just a few minutes and helps protect injectors, maintain peak fuel pressure, and ensure clean, water-free diesel.
A typical filter change is straightforward:
- Shut the system off and relieve pressure.
- Unscrew the old filters (Fuel/Water Separator and Particulate Filter).
- Lubricate and spin on the new filters until snug.
- Prime and check for leaks.
That’s it—your truck is ready to hit the road with maximum protection.
Individual Filters, Filter Packs, and Drop-In Series Options
FASS makes it easy to choose the filter replacement that fits your maintenance style and budget:
- Individual Filters – Perfect when you only need to replace a single Fuel/Water Separator or Particulate Filter. Available in multiple micron ratings for custom filtration needs.
- Filter Packs – A convenient bundle that includes everything for a complete filter service in one part number. Stock up and save time.
- Drop-In Series Fuel Filters – Engineered for FASS Drop-In Series Fuel Systems, these filters maximize fuel quality and simplify maintenance for modern L5P Duramax, 6.7 Powerstroke, and late-model Cummins applications.
By using genuine FASS filters, you keep your warranty intact and maintain the 2-micron filtration and air/vapor removal that FASS systems are famous for.
