Fitment gate — Caterpillar gates C15 and 3406E injector fitment by engine serial prefix. Read the part number off the injector you are removing and match it, or provide your engine serial number with your order.

Second fitment gate — the C15 was built in pre-ACERT and ACERT versions using different injectors. Confirm which your engine is before ordering a set.

Installation note — HEUI injectors depend on the high-pressure oil system. A failing high-pressure oil pump produces symptoms similar to failed injectors, so confirm the oil system before condemning the injectors.

Full disassembly, 100% nozzle replacement, and end-of-line testing to OEM specification restore the fuel atomization and delivery the engine depends on. Provide your engine serial number before ordering a set.
