Specs At A Glance

Good To Know

Q: Does this pump need coding after installation? A: Some ISB 6.7L applications require calibration with a scan tool after the pump is installed. Confirm the procedure for your engine before startup.

Q: Should I replace the fuel filter at the same time? A: A new filter and clean lines protect the new pump from debris. Contaminated fuel is a common cause of injection pump failure.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
