Denso original 295050-1401 Diesel Fuel Injector Assy for 4HK1 6HK1 Engine Car Truck Vehicle Replacement for OEM 295050-1400 8-982384263-1 original new injector

The DENSO 295050-1401 is an original-type common rail diesel fuel injector engineered to deliver precise fuel metering and consistent high-pressure atomization for ISUZU 4HK1 and 6HK1 diesel engines. Designed for selected ISUZU trucks, ISUZU industrial engine platforms, and Hitachi excavators such as the ZX250-5A search application, this injector supports reliable operation across on-road fleet service, construction machinery, engine overhaul, and export parts supply channels. With full ECU-controlled injection control over pressure, timing, rate, and quantity, the unit matches DENSO common rail calibration standards and is bench-testable prior to installation, ensuring direct OE replacement performance under demanding load conditions.

Manufactured to match OE 8-98238463-1 / 8982384631 specifications, the 295050-1401 injector features export-friendly part-number matching and robust construction suitable for heavy-duty diesel environments. It is commonly referenced as 2950501401, 8-98238463-1, and 8982384631 in global aftermarket and OEM replacement catalogs. The injector's high fuel pressure capability and high injection precision contribute to stable cold starts, smooth idle quality, efficient combustion, and reduced exhaust emissions. Its compatibility with ISUZU 2 Series search applications, ISUZU trucks, and Hitachi construction equipment makes it a trusted solution for distributors, repair workshops, and fleet maintenance operations.

Proper installation and maintenance are essential for long service life. Operators should use clean diesel fuel, replace the fuel filter and sealing washer regularly, service the water separator, and keep the fuel tank and common rail system free of contamination. After installation, follow the official service manual torque specifications, inspect high-pressure pipes, clean the injector seat, perform injector coding if required, and complete leak testing along with ECU live-data verification. Most early failures are caused by contaminated fuel, water ingress, metal particles, incorrect installation, reused sealing washers, wrong coding, or a contaminated high-pressure fuel system. Correct diagnosis should include ECU scanning, rail-pressure check, injector return-flow test, electrical test, cylinder balance check, compression check, boost test, aftertreatment scan, and professional common rail bench testing to confirm injector performance.
