Caterpillar C7 Series Fuel Injector 238-8091 Product Detail Page Description Product Overview The Caterpillar 238-8091 fuel injector, also written as 2388091, is a diesel fuel injector assembly used for CAT C7 Series diesel engine service, rebuild, maintenance, and replacement applications. It is commonly listed in the aftermarket as a replacement or cross-reference injector for numbers including 10R-4763, 20R-8059, 233-3535, 236-0974, 241-3400, 295-1410, 328-2582, and 387-9428. Multiple aftermarket suppliers list this injector for Caterpillar C7 applications, and some listings also associate related replacement coverage with 3126B, C9, or specific Caterpillar equipment applications, so final fitment should always be verified by engine serial number, injector number, and equipment model before installation. This product is designed for professional diesel repair markets, heavy equipment maintenance companies, fleet workshops, engine rebuilders, diesel parts distributors, mining and construction maintenance teams, agricultural equipment service companies, and global aftermarket replacement programs. The CAT C7 fuel system is commonly associated with HEUI-type hydraulic electronic unit injector technology in many service markets. Some online aftermarket listings describe the 238-8091 injector as HEUI, while at least one listing describes it as common rail; because of this inconsistency, buyers should confirm the exact system type with the engine serial number and original injector removed from the engine before purchase.
