Performance Characteristics

The filter’s low pressure drop ensures that engine performance is not compromised while providing robust protection against particulate matter. Its ability to handle high temperatures and a wide range of fuel types makes it suitable for both everyday driving and heavy-duty service.

Installation & Maintenance

1. Preparation: Disconnect the battery, relieve fuel system pressure, and remove the old filter cartridge.
2. Bootjack Removal: Slide the Bootjack lever to release the retaining clip. The cartridge can then be pulled out without force.
3. Insertion: Align the new KX338/22D cartridge with the fuel line, ensuring that the boot is seated correctly. Insert until fully engaged.
4. Securing: Tighten the Bootjack lever to lock the cartridge in place. Verify that no gaps or leaks are present.
5. Testing: Reconnect the battery, restore fuel pressure, and start the engine. Check for proper operation and absence of abnormal noises.

Because the filter is a cartridge design, replacement can be performed in under five minutes by trained technicians, minimizing vehicle downtime.
