Description
Fleetguard FS19966 is a spin-on fuel/water separator for Volvo D11 and D13 engines and Mack MP7 and MP8 platforms (pre-EPA17). Cummins Filtration is the OEM filter supplier for Volvo and Mack, and the FS19966 separates water and removes particulate contamination before fuel reaches the high-pressure injection system, protecting injectors from premature wear.
