Caterpillar C13 Fuel Injector 332-1419 Product Detail Page Professional Product Overview The Caterpillar C13 Fuel Injector 332-1419, also searched as CAT 3321419 injector, C13 injector 332-1419, Caterpillar injector group fuel 332-1419, and CAT C13 diesel injector replacement, is a heavy-duty fuel injection component used in Caterpillar C13 diesel engine applications. It is designed for demanding industrial diesel operating environments where fuel delivery accuracy, combustion stability, injector durability, and engine reliability are critical. According to Caterpillar’s official parts channel, Cat fuel injectors are developed specifically for Cat engines and for modern low-sulfur, low-lubricity diesel fuel conditions. Caterpillar also describes its fuel injectors as being engineered for wear life, fuel economy, overall performance, coated plunger wear resistance, and rigorous testing for genuine Cat reliability. This injector is commonly associated in aftermarket and supply-chain listings with the Caterpillar C13 engine, and multiple industrial diesel injector suppliers list 332-1419 / 3321419 together with cross references such as 20R-2437, 10R-3258, 10R-2977, 10R-6162, 212-3462, 10R-0961, 212-3463, and 10R-7236. These cross numbers should be used as search, procurement, and reference numbers, but final fitment should always be confirmed by engine serial number, original injector number, ECM calibration, and machine application. The Caterpillar C13 engine family is widely used in industrial power, construction machinery, generator sets, heavy-duty trucks, and special-purpose equipment. Caterpillar lists current C13 industrial diesel engine ratings around 287–400 kW / 385–536 hp depending on configuration and emissions market, while other Caterpillar C13 ACERT industrial data lists ratings around 287–388 bkW / 385–520 bhp.
