Denso original Fuel Injector 295050-1900 Replacement for OEM 8982601090 Isuzu 4JJ1 Diesel Engine G3 Series Common Rail Injection Valve original new injector

The DENSO Common Rail Fuel Injector 295050-1900 is engineered as a direct OE replacement for the ISUZU 4JK1 2.5L Euro 5 diesel engine, covering D-Max II 2.5 CRDi, D-Max II 2.5 CRDi 4WD, and D-Max II Platform/Chassis TFR / TFS pickup and light commercial applications. The authorized cross-reference list includes DCRI301900, 295050-0911, 8-98260109-0 through 8-98260109-9, 8982601090 through 8982601099, and 8-98159583-0 through 8-98159583-9, supporting flexible part identification across workshops, distributors, and fleet maintenance operations.

Designed to deliver precise fuel metering, fine atomization, and stable combustion, this electronically controlled high-pressure common rail injector restores original engine performance. Installation should follow OEM service manual torque specifications, with replacement of the copper washer, O-ring, and seals, plus fuel system bleeding, rail pressure monitoring, and ECU injector coding or registration to ensure proper function.

To maximize service life, clean diesel fuel is recommended along with regular fuel filter replacement, water separator draining, and clean fuel tank and line maintenance. When symptoms such as hard starting, black or white smoke, rough idle, power loss, excessive return flow, or rail pressure fluctuation occur, return-flow testing, injector balance testing, and test bench inspection should be performed before replacing unrelated components.
