Caterpillar original Diesel Fuel Injector Replacement 392-2000 392-0201 392-0202 392-0204 Common Rail Injector, for heavy duty diesel engine application original new injector

Sourced to meet strict Caterpillar OEM specifications, the CAT-branded 392-2000 fuel injector is a purpose-engineered high-pressure fuel delivery component designed exclusively for CAT 3512B V12 diesel engines within the CAT 3500 Series. This new, OEM-grade assembly is constructed from high-strength alloy steel, adheres to official OEM dimensional and performance standards, and comes with a 12-month warranty for industrial B2B use. It requires OEM trim calibration to ensure full compatibility with the engine’s factory control system.

Engineered as an electronic/mechanical high-pressure injector, the 392-2000 features a precision multi-hole spray nozzle, high-temperature seal sets, and industrial-grade corrosion resistance to operate reliably in extreme working conditions. It delivers precisely metered diesel fuel with fine, consistent atomization, which improves combustion efficiency, reduces fuel consumption and smoke emissions, stabilizes power output, and extends long-term engine reliability. It is fully compatible with CAT diesel ECM systems for regulated injection timing and duration.

This injector supports all standard, marine, heavy-duty, offshore, mining, and oilfield configurations of the CAT 3512B, and suits generator sets, marine propulsion systems, mining vehicles, industrial power plants, construction equipment, and oilfield power modules across marine, power generation, mining, oil & gas, and industrial sectors. Its full cross-reference coverage streamlines parts lookup and replacement across global industrial supply chains for distributors, maintenance teams, and equipment operators.
