Denso original Replacement for OEM 095000-6367 Fuel Injector 4HK1 Engine Excavator Fuel System Parts Injector Pump Diesel original new injector

The DENSO 8-97609788-7 common rail fuel injector is engineered as a direct OE replacement for ISUZU 4HK1 and 6HK1 diesel engines, with authorized cross references 095000-6367, 095000-6360, 095000-6366, 8976097883, 8976097886, 9709500-636, 095000-6361, 095000-6362, and 095000-6363. It is suitable for ISUZU 2 Series commercial trucks and excavator applications where the original injector part number matches, providing a reliable fit for engine repair, injector service workshops, and fleet maintenance operations in B2B export catalogues.

Built on DENSO common rail technology, this electronically controlled injector delivers precise fuel quantity and injection timing under high-pressure common rail conditions, supporting stable combustion, consistent rail pressure, and efficient engine performance across demanding industrial and commercial duty cycles. The injector assembly is designed to integrate with the existing fuel return lines, electrical connector, and high-pressure rail connections of the ISUZU 4HK1 and 6HK1 platforms without modification.

Proper service procedure requires clean diesel, regular fuel filter replacement, water contamination prevention, and protection of the electrical connector. Before replacement, the complete common rail system should be diagnosed to rule out fuel contamination, air ingress, pump debris, and return-line issues. Fault symptoms including hard starting, rough idle, black smoke, power loss, high fuel consumption, rail-pressure fault codes, and limp mode should be evaluated through leak-off testing, rail-pressure monitoring, injector correction-value reading, wiring inspection, and injector bench testing.
