original 295050-2400 Common Rail Fuel Injector 433-6862 4336862 for C7.1 Engine 312E 314E 25D 535D High Pressure Diesel Injector Replacement for OEM original new injector

Engineered for demanding diesel powertrains, this Denso common rail fuel injector (OE 295050-2400, cross reference 433-6862) delivers precise atomization and consistent fuel metering across the full engine operating range. Designed as a direct OEM replacement for C4.4 and C7.1 industrial diesel engines, the assembly supports the high-pressure injection cycles required by modern electronically controlled fuel systems used in heavy equipment, generator sets, agricultural machinery, and marine auxiliary power units.

Each injector features precision-machined nozzles, a high-pressure tolerant body, and a stable solenoid actuator that ensures repeatable response times under continuous duty. Corrosion- and wear-resistant internals extend service life in harsh operating environments, while factory calibration guarantees fuel delivery accuracy that meets original equipment specification. The unit is fully compatible with the C4.4 ACERT and C7.1 Industrial Series platforms, supporting excavators (305E2, 307E2), backhoe loaders (416F2), power generation packages, and industrial engine assemblies.

To maximize injector service life, operators should replace fuel filters at recommended intervals, use only high-quality diesel fuel, and maintain a clean fuel tank free of contaminants. Routine ECU diagnostics help identify performance drift before failure occurs. Common troubleshooting indicators include DTC fault codes, changes in exhaust smoke color, and abnormal engine noise. This OEM replacement injector provides a reliable, cost-effective solution for fleet maintenance, workshop rebuilds, and industrial engine overhauls.
