Vehicle application alone does not guarantee fitment. Verify the engine and injector part number before ordering.
IMPORTANT INSTALLATION INFORMATION
XPI injectors require proper calibration and installation procedures. Injector trim codes should be programmed into the ECM as required after installation.
When servicing the high-pressure fuel system, follow the appropriate Cummins installation procedures and maintain strict fuel-system cleanliness.
Inspect related fuel-system components and replace required seals, O-rings, washers, and other one-time-use installation components as specified by the engine manufacturer.
VERIFY FITMENT
Fitment can vary by Engine Serial Number (ESN), CPL, ECM calibration, emissions configuration, and original injector part number.
Verify 4327147 or a compatible cross-reference number before ordering. If you’re unsure about fitment, contact Samperio Turbo Rebuild with your ESN, CPL, or original injector number.
