Description
The PAI 209967X is a remanufactured fuel injector for Cummins M11 and ISM diesel engines with the Celect electronic unit-injection fuel system. It replaces Cummins 3411754 (reman 3411754RX) and earlier number 3087772, restoring correct fuel metering, injection timing, and atomization on these 10.8L workhorses. As a remanufactured exchange unit (X suffix), a refundable core charge applies — return your rebuildable core for credit. Celect injectors are calibration-matched — when replacing more than one, use injectors of the same part number across the bank.
Symptoms of a Failing Injector
- Rough idle, misfire, or engine shake at low RPM
- Hard starting and long crank times
- White smoke on start-up or black smoke under load
- Fuel knock, hesitation, and low power
- Falling fuel economy
- Fuel dilution of the engine oil from a leaking injector
