The engine dataplate shows important facts about your engine. The engine serial number and control Parts List (CPL) provide data for ordering parts and service. The engine dataplate must not be changed unless approved by Cummins Inc.

The dataplate is located on the fuel pump side of the engine, on the rocker housing. Have the following engine data available when communicating with a Cummins Authorized Repair Location.

NOTE: The ECM referenced here is used with the CELECT™ and CELECT™ Plus fuel systems only.

There are two dataplates on top of the ECM.

The dataplate on the left contains the part number (P/N), serial number (S/N), and date code (D/C) of the ECM.

The dataplate on the right contains the engine serial number (ESN), fuel code (FC), and engine calibration information.

NOTE: The fuel pump dataplate referenced here is the style dataplate used on a Cummins PT® (pressure/time) fuel pump. This is the type fuel pump used on a STC fuel system. It is not used on fuel pumps with the CELECT™ or CELECT™ Plus fuel systems.

The fuel pump dataplate is located on the top of the fuel pump. It provides information for fuel pump calibration.
