original 4P-9075 Common Rail Diesel Fuel Injector for 3508 3512 3516 3524 Diesel Engine Construction Machinery Engineering Equipment Injectors 4P9075 4P-9076 original new injector

Engineered for heavy-duty diesel power systems, the 4P-9075 fuel injector delivers precision fuel metering and stable injection performance across demanding industrial applications. Cross-referenced with 0R-3051, OR3051, CA4P9075, 7E3381, and 9Y4543, this injector assembly is a direct-fit replacement for 3512A, 3508C, 3508B, 3512B, 3516B, 3516C and other 3500 Series engines used in generator sets, marine propulsion, mining machinery and oilfield power units.

The injector features an optimized spray pattern for efficient high-pressure diesel atomization, wear-resistant internal components, and industrial-grade materials designed for high temperature and high pressure operating conditions. Its OEM-style fitment ensures reliable integration into SR4 and SR4B power generation systems, offshore power units, emergency standby installations, compressor drives and pump drives. Rebuild-friendly construction supports long service life and reduces total ownership cost. Global compatibility makes it suitable for markets across North America, South America, Europe, the Middle East, Africa, Australia and Southeast Asia, covering data center backup power, copper mining, drilling operations, marine fleets and remote power generation facilities.

For optimal performance, use clean diesel fuel, replace fuel filters on schedule, drain the water separator and test injectors during engine overhaul. Replacing injectors as a matched set on high-hour engines improves fuel balance and reduces combustion variation. Before purchasing, confirm compatibility using engine serial number, arrangement number, old injector number and photos.
