FAQ

Q1: How do I confirm this injector (0445120199) will fit my engine?
A: Please check the existing part number on your old injector. It should match either 0445120199 or 4994541. Also, verify your engine model (e.g., Cummins ISX, ISB). If you are unsure, provide us with your engine serial number for cross-verification.

Q2: What are the installation precautions for this common rail injector?
A: Installation should be performed by a qualified mechanic. Ensure the fuel system is depressurized before removal. Always replace the copper washer and O-rings with new ones (included in the package).
