Description
Wix WF10579 is a cartridge-style fuel/water separator that drops into the integrated cassette housing on 2019 and newer Ram 2500/3500 6.7L Cummins and 3.0L EcoDiesel pickups. It replaces the Mopar/Chrysler 68436631AA service cartridge directly and uses Wix’s synthetic media to protect Bosch CP4 and CP3 high-pressure injection components from particulate and water contamination.
Signs You Need a New Fuel Filter
- Loss of power under load or extended cranking on cold start
- Water-in-fuel (WIF) light illuminated on the dash
- Engine hesitation, surging, or rough idle
- Reduced fuel economy or check-engine light with fuel-system codes
- Service interval reached (typically every 15,000 mi / 1 yr on 6.7L Cummins)
