OrderECM stocks diesel fuel injectors for the full range of heavy-duty diesel engines, covering Hydraulic Electronic Unit Injectors (HEUI), High Pressure Common Rail (HPCR) injectors, mechanical unit injectors, and Bosch common rail injectors. Correct injector replacement is critical for fuel economy, emissions compliance, and engine longevity — every injector in our stock is matched to the engine model, serial number range, and applicable emissions tier.
CAT HEUI injectors require injector trim code (ITC) programming via CAT ET software after installation. Cummins HPCR injectors require calibration code entry via INSITE. We supply the injector part number and trim code details with every unit shipped.
