Cummins N14 – Fuel Pump – Cleaning and Inspection for Reuse

When removing the fuel pump from step timing control (STC) engines, check to make sure the same Control
Parts List (CPL) number is on both the fuel pump dataplate and the engine dataplate.
If the CPL number on the fuel pump dataplate does not match the CPL number on the engine dataplate, the fuel
pump must be calibrated again to the correct specification for the engine.
