Genuine Fleetguard FF266 NanoNet Cartridge Fuel Filter | Cummins 5335504

Genuine Fleetguard FF266 NanoNet Cartridge Fuel Filter

This one is in the factory Cummins Filtration poly bag with Cummins branding on the print, and FF266 written on the outside in marker so it could be found on the shelf without opening anything.

FF266 is a cartridge, not a spin-on. It drops into an OS497 style filter head and uses Fleetguard NanoNet media, which is the layered synthetic build Cummins developed for common rail engines. Common rail injectors run clearances measured in single digit microns, so the media has to hold very fine particulate without choking flow.

What it does

• Cartridge style fuel element for OS497 series filter heads
• NanoNet layered synthetic media built for high pressure common rail fuel systems
• Published cross reference includes Cummins 5335504
• Protects injectors where a nominal pleated paper element would let damaging fines through

• Primary application: Cummins common rail engines using OS497 filter heads
• Fleetguard part number: FF266
• Cross reference: Cummins 5335504
