Caterpillar original 294-3500 Fuel Injector, Engine Injectors Gp-Fuel, Diesel Common Rail Injector for Construction Machinery and Truck, Replacement for OEM, fits C15 C18 Diesel original new injector

Engineered for the Caterpillar Electronic Unit Injection (EUI) system, the 294-3500 fuel injector assembly delivers precisely metered, finely atomized diesel fuel directly at the cylinder head. Built to OEM specifications from high-strength alloy steel, this electronically controlled injector supports accurate injection timing, stable fuel delivery, and complete combustion, helping engines sustain rated horsepower, torque output, and fuel efficiency under severe high-load operating conditions.

The injector is a direct replacement for Caterpillar C15, C15 ACERT, and C16 diesel engines, with selected applications on the 3406E platform as well as industrial power units, generator engines, and marine engines. It cross-references 2943500, 10R-8501, 10R8501, 387-9433, 3879433, 295-1408, 2951408, 328-2576, 3282576, 387-9427, and 3879427, simplifying sourcing for fleets and parts distributors. Equipment coverage spans heavy-duty trucks, mining trucks, excavators, wheel loaders, dozers, generator sets, oilfield equipment, marine propulsion systems, and industrial compressors across the construction, mining, marine, and power generation industries.

Every unit is calibration and performance tested to OEM-level standards, ensuring consistent spray patterns and dependable operation in demanding environments. High-temperature resistance and corrosion-protected components extend service life in harsh industrial and marine conditions, while optimized atomization contributes to lower fuel consumption and reduced emissions. Available in new, OEM-equivalent, and remanufactured conditions, the 294-3500 gives maintenance teams and overhaul programs flexible, cost-effective procurement options without compromising reliability.
