Q: Is this a new or remanufactured part?
A: This is a new, aftermarket replacement part manufactured to OEM specifications. It is not a remanufactured or used core.

Q: What is required for proper installation and calibration?
A: Installation of a high-pressure fuel injection pump is a precision task. It requires specialized tools, a clean environment, and often needs professional calibration/timing after installation. We recommend installation by a certified diesel technician to ensure optimal performance and avoid engine damage.
