The official Cat Parts listing identifies 166-0149 as a Cat Injector GP-Fuel, and Caterpillar states that Cat fuel injectors are developed for Cat engines and modern low-sulfur, low-lubricity diesel fuels.
This product is designed for diesel fuel atomization, controlled injection timing, combustion stability, engine power recovery, fuel economy support, and long-term industrial service reliability. It is suitable for customers looking for a replacement injector, remanufactured injector, aftermarket injector, marine injector, or spare parts solution for Caterpillar C12 diesel engine maintenance.
Important fitment note: Always confirm the injector by engine serial number, machine model, original injector number, ECM calibration, and service manual data before purchase. Online sellers commonly list this injector with C10, C12, 3176, and 3196 engines, but final compatibility must be verified by the customer’s engine data plate or parts system.
