FAQ

Q1: Is this injector a direct fit for my Cummins 6.7L engine?
A: Yes, the 0445120329 / 5267035 injector is a standard OE replacement for many Cummins 6.7L ISB engines (2007–2018). However, we recommend checking your engine’s serial number and comparing the injector code to confirm compatibility, as some variants may require different calibration.

Q2: Do I need to replace the injector copper washers and o-rings during installation?
A: Yes, we strongly recommend replacing all sealing washers, o-rings, and hold-down bolts with new ones to prevent fuel leaks and ensure proper injector seating. These are not included with the injector and should be sourced separately.

Q3: What is the recommended maintenance schedule for these injectors?
A: Common rail injectors typically require inspection every 100,000 miles or 3,000 hours of operation. Key maintenance includes checking fuel filter condition, testing fuel pressure, and performing injector return flow tests to detect wear early. Always use high-quality diesel fuel and maintain a clean fuel system to maximize injector lifespan.
