OEM paper filters are rated nominally at 7 10 m, meaning they let significantly more particulate through to your CP4.2 high-pressure pump Water Separation: 98% removal efficiency the hydrophobic layer strips emulsified water from diesel fuel, critical for protecting the CP4.2 injection pump from cavitation erosion and catastrophic failure O-Rings: 2 premium Viton fluoroelastomer O-rings (1 large cap seal, 1 small filter seal) rated to 400 F continuous, compatible with ULSD, B20 biodiesel, and common diesel fuel additives Service Interval: Replace every 15,000 22,500 miles (24,000 36,000 km).

Dry O-rings can pinch, tear, or roll during installation all of which cause air leaks and hard-start conditions. TORQUE TO SPEC: If you're using the OEM plastic cap, torque to 18 ft-lbs (25 N m) no more. If you're using an iFJF billet aluminum cap, the same torque spec applies, but the aluminum cap won't crack if
