Engineered as a direct-fit replacement injector for the 3512A engine platform, the 7E-3382 fuel injector delivers OEM-equivalent fuel metering accuracy and atomization performance. Each unit is precision CNC machined from high-strength alloy steel, then 100% performance tested to verify injection pressure up to 2200 Bar, spray pattern integrity, and flow rates. The hardened multi-hole nozzle design ensures consistent fuel delivery across the full load range of the 3512, 3512A, and 3512B engine families, supporting both marine propulsion and stationary power generation duty cycles.

This injector is built for sustained operation in harsh industrial environments, including high-temperature continuous running, corrosive marine atmospheres, and dust-heavy mining sites. Its corrosion-resistant surface treatment, heavy-duty internal components, and tight OEM dimensional tolerances contribute to extended service intervals and reduced unscheduled downtime. Operators of industrial generator sets, oilfield drilling systems, and heavy construction machinery can rely on stable fuel delivery, reduced exhaust smoke, and balanced cylinder performance when this 7E-3382 unit is installed.

Routine maintenance includes using clean diesel fuel, regular fuel filter replacement, periodic injector testing during major overhauls, and following the correct installation sequence: relieve fuel pressure, remove the old injector, clean the injector bore, install new sealing components, torque the 7E-3382 to specification, bleed the fuel system, and verify no leakage on startup. Backed by a 12-month warranty and manufactured to global export standards, this injector provides a reliable, cost-effective solution for keeping 3512A series engines running at peak efficiency.
