The DENSO common rail fuel injector 095000-5431 is built for the ISUZU 4JJ1, 4JJ1-TC, and 4JJ1-TCX 3.0L diesel engines installed in D-Max, Rodeo, and KB300 pickup trucks. Within the electronically controlled high-pressure common rail fuel system, it works together with the fuel pump, common rail, and ECU to deliver precisely metered diesel at the correct timing into each combustion chamber, supporting fine atomization, stable combustion, and consistent engine performance.

The authorized OE number is 095000-5431, and this injector fully cross-references the family including 095000-5430, 095000-5432, 095000-5433, 095000-5434, 095000-5435, 095000-5439, 8-97311372-0, 8-97311372-1, 8-97311372-2, 8-97311372-3, 8-97311372-4, 8-97311372-5, 897311372, 8973113720, 8973113721, 8973113722, 8973113723, and 8973113725. Before installation, the OE number, cross reference, engine model, vehicle model, VIN, and engine serial number should always be confirmed to ensure correct fitment and reliable replacement.

Before fitting, clean the injector bore and seat, replace copper washers, O-rings, and seals, then bleed the fuel system and carry out injector coding if the ECU requires it. If the engine shows hard starting, black or white smoke, rough idle, low power, high fuel consumption, or excessive return fuel, return-flow testing, rail-pressure checking, and test-bench evaluation are recommended to confirm injector condition.
