Engineered to meet the exacting demands of Cummins N14 diesel power systems, the 3080766 fuel injector delivers dependable performance across on-highway, industrial, and marine platforms. Manufactured to OEM precision standards, this injector assembly ensures accurate fuel atomization and consistent injection timing, supporting stable combustion under continuous heavy-duty operation.

Built from high-strength alloy materials, the 3080766 provides excellent corrosion resistance, wear resistance, and high-temperature durability for extended service life. It serves as a direct replacement for cross reference numbers 3411765, 3411766, 3803528, and 3803749, and fits Cummins N14, N14 STC, N14 Plus, N14 Celect, and N14 Celect Plus engines. Key performance benefits include improved fuel atomization, higher combustion efficiency, increased engine power, reduced fuel consumption, lower exhaust emissions, enhanced cold-start capability, and stable idle operation.

This injector is widely applied in Kenworth, Peterbilt, Freightliner, and Western Star trucks, as well as generator sets, oilfield, mining, marine, and construction equipment. To maximize reliability, use high-quality diesel fuel, replace fuel filters regularly, avoid water contamination, monitor fuel pressure, and conduct periodic injector testing. Common symptoms such as difficult starting, excessive smoke, power reduction, increased fuel consumption, or rough idle indicate that injector inspection and flow testing should be performed immediately to protect overall engine efficiency.
