Description
The PAI Industries 209992X is a remanufactured electronic unit injector for Cummins N14 diesel engines with the Celect fuel system. It replaces Cummins injector 3411765 and the reman service numbers 3411765PX and 3411765RX. Each exchange injector is rebuilt, flow-calibrated, and pressure-tested to restore fuel delivery, injection timing, and cylinder balance in on-highway N14 applications. N14 injector fitment is CPL-specific — confirm against your engine dataplate before ordering. A refundable core charge applies.
Symptoms of a Failing N14 Unit Injector
- Rough idle and cylinder misfire, often flagged by a cylinder cutout test
- Low power and sluggish acceleration under load
- White or black exhaust smoke
- Fuel knock or audible injector rattle
- Fuel in the engine oil (rising oil level or diesel smell)
- Excessive fuel consumption
