original 6L4355 Fuel Injector Assembly for 3512 3512A E3512 Diesel Engine Injection System Replacement for OEM 4P9075 4P9076 7E6408 4P9077 9Y3773 original new injector

Engineered for demanding industrial diesel applications, the 6L4355 fuel injector delivers OEM-level performance for 3500 Series engines including 3508, 3508B, 3512, 3512A, 3512B, 3516, 3516B, and 3516C models. Manufactured from high strength alloy steel, this mechanical fuel injector is designed to withstand the extended operating hours, high load factors, and challenging environmental conditions typical of prime power stations, marine propulsion systems, mining haul trucks, and oilfield drilling rigs. The injector directly interchanges with reference numbers 6L-4355, 0R8684, 4W7018, 8N7005, 7W5929, 7E6408, 4W7019, and 8N7006.

Key performance advantages include precise fuel metering, optimized combustion efficiency, reduced fuel consumption, improved power output, lower exhaust emissions, and enhanced engine reliability. Calibrated to maintain accurate fuel delivery throughout its service life, the unit installs into the cylinder head position and supports stable atomization across variable load conditions. Typical applications cover emergency backup power, utility generation, commercial vessels, tugboats, offshore supply vessels, fracturing equipment, compression systems, and heavy manufacturing facilities.

For optimal service life, clean the injector bore before installation, replace sealing washers, apply OEM torque specifications, verify fuel line cleanliness, and bleed the fuel system prior to performance testing. Recommended diagnostics: black smoke indicates nozzle wear, white smoke suggests leakage, power loss points to injection pressure, hard starting relates to fuel delivery, and high fuel consumption warrants calibration testing.
