Cummins 3968846 Common Rail Fuel Injector Assembly - Used

Cummins common-rail fuel injector assembly, Cummins part number 3968846 per the original Genuine Cummins Parts box label. Application: commonly associated with the Cummins mid-range common-rail family (ISB/QSB 5.9-class) — exact engine model, CPL, and marine vs. industrial application are NOT verified and must be looked up by engine serial number. Condition: used and untested. The injector is complete in appearance (solenoid cap with terminal stud, hold-down flange, body O-rings present) with light handling marks, shop dirt and light discoloration at the nozzle tip. It has not been flow tested, pop tested, or calibrated — it is not sold as new, rebuilt, or reman. We recommend bench testing and calibration by a qualified diesel injection shop, plus new copper sealing washer and O-rings, before installation. Residual fuel may be present; the unit is wiped down and the inlet and nozzle capped before shipping. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
