19100-04173 PUMP ASSY, INJECTI Denso Cross

Introduction
Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.MEUI-C fuel injectors installed in certain C13 and C15 truck engines have failed due to issues not related to materials or workmanship of the injector. Injector solenoid failures have occurred due to fuel system restrictions and connector pin arcing. Other injector failures have been related to incorrect injector rocker preload. To prevent more failures, further troubleshooting and inspection of the fuel system and electrical connectors is necessary to determine the root cause of the solenoid failure. Likewise, if injector tappet or injector rocker failures are observed, investigations should review that correct injector preload procedures were followed.Note: Failures of injectors that are not due to defects in manufacturing or materials may not be warrantable failures.
