Denso original 095000-5500 Common Rail Fuel Injector for 4HL1 6HL1 Diesel Engine Replacement for 8-97367552-1 8973675525 original new injector

The DENSO Common Rail Fuel Injector 095000-5500 is engineered as an original-type replacement for ISUZU 4HL1 and 6HL1 diesel engines used in ISUZU F Series commercial trucks and related diesel applications. Built on DENSO common rail technology, the injector operates within a high-pressure common rail fuel system to deliver precise fuel atomization and consistent injection performance. It supports high fuel pressure, accurate injection timing, stable injection rate, and controlled injection quantity, contributing to improved fuel economy, reduced emissions, lower engine noise, and reliable power output across demanding commercial diesel operating conditions.

This injector family provides extensive part-number coverage for the 095000-550# and 897367552# ranges, including part numbers 095000-5500, 095000-5501, 095000-5502, 095000-5503, 095000-5504, 095000-5505, 095000-5506, 8-97367552-0, 8-97367552-1, 8-97367552-5, 8-97367552-6, 9709500-550, 9709500550, 8973675520, 8973675521, 8973675525, and 8973675526. The wide cross-reference coverage makes the unit suitable for ISUZU diesel repair workshops, injector service centers, engine overhaul operations, fleet maintenance programs, and B2B export spare parts catalogues serving international commercial vehicle markets.

Before installation, the injector part number, OE number, engine code, vehicle model, VIN or chassis number, connector type, and any coding requirement must be confirmed. The fuel system should be clean, the fuel filter replaced, the injector seat cleaned, and all sealing components renewed. Common injector-related symptoms such as hard starting, rough idle, power loss, black smoke, high fuel consumption, and rail-pressure fault codes are frequently caused by fuel contamination, water in diesel, air ingress, or poor filtration. After installation, perform fuel bleeding, leak inspection, diagnostic scanning, injector coding when required, and a road test to verify proper operation.
