Perkins original Perkins 359-4050 Fuel Injector 3594050 Replacement for C15 C27 C32 Caterpillar series new injector original new injector

The Perkins fuel injector 359-4050 is engineered as a direct OE replacement for Perkins C15 and C18 diesel engines, delivering accurate fuel metering, controlled injection timing, and reliable combustion performance. Designed for both original and remanufactured service channels, the 359-4050 fuel injector group supports consistent engine starting, smooth idle quality, stable power output, improved fuel efficiency, and reduced exhaust smoke across heavy-duty operating conditions. Its mechanical electronic injector design incorporates coated plunger wear resistance and low-sulfur fuel compatibility, ensuring durability in demanding industrial environments.

This injector is cross-referenced with Perkins part numbers 20R-1308, CA3594050, 703750AT, and 703751AT, along with extended cross references 253-0615, 253-0617, 10R-1000, 10R-7229, 10R-0956, 10R-0958, 229-5919, 211-3027, 211-3024, 232-1199, 249-0709, 235-1401, 10R-8502, 20R-5353, and 20R-2285, simplifying part identification across distributor and remanufacturer networks. It is suitable for D11, D11T, 777 series, 992K, 854K, MD6250, and MD6310 equipment, serving construction, mining, marine, oilfield, and generator set applications worldwide. Fitment must be confirmed through engine serial number, engine arrangement number, and original injector tag.

Proper maintenance is essential to maximize injector service life. Operators should use clean diesel, replace fuel filters at recommended intervals, drain water separators, and inspect electrical connectors, fuel return lines, and injector seats regularly. When symptoms such as hard starting, rough idle, misfire, black or white smoke, power loss, high fuel consumption, or fuel dilution in oil occur, diagnostic scanning, cylinder balance testing, and injector bench testing are recommended. Injectors should be replaced as a matched set when engine condition requires it, preserving combustion balance and long-term reliability.
