Description
Fleetguard FS20022 spin-on fuel/water separator for Cummins QSB 6.7L industrial engines and JCB 320-series engines, replacing Cummins 3978134 and JCB 32/926107. StrataPore media filters at 25 microns and 96% TWA efficiency (SAE J1985), with 90% free and emulsified water separation; a slow-release lubricity additive helps offset the lower-sulfur diesel duty cycle. Mounts on a 1 1/8-16 UN-2B bowl — the JCB backhoe and excavator service filter for Cummins-powered models.
Signs You Need a New Fuel/Water Separator
- Water-in-fuel warning light or visible water in the bowl
- Hard starting or extended cranking, especially in cold weather
- Loss of power, surging, or rough idle under load
- Decreased fuel economy or excessive exhaust smoke
