(1 pc) High-Pressure Common Rail Electronic Fuel Injector 5263321 Compatible with Cummins ISLe QSL9 Heavy-Duty Truck and Loader Diesel Injector Assembly

5263321 is designed for Cummins ISLe/QSL9 engine high-pressure common-rail electronically controlled fuel injectors. The rear of the injector is equipped with a heavy-duty, waterproof dual-needle solenoid valve. The vehicle’s ECU precisely controls the multi-stage injection timing—including pre-injection, main injection, and post-injection—as well as the cyclic fuel delivery volume, making it compatible with 1400–1600 bar high-pressure common-rail fuel systems. It features a high-flow, multi-hole swirl nozzle with a layered atomization design, balancing power output for mining, long-haul heavy-duty, and continuous high-load applications while meeting Euro 3 and US Tier 3 emissions regulations.

6-month warranty. Damage caused by accidental impact, high-temperature scorching, rough disassembly or installation, or prolonged use of low-quality diesel fuel is not covered under the warranty.
