original 348-4090 Common Rail electronic Diesel Fuel Injector Assembly Diesel Parts for C13 Engine E345C E349D new injector original new injector

The C13 Fuel Injector 348-4090 is engineered specifically for C13 diesel engines, delivering OE-level compatibility across the C13 Industrial Engine, C13 XQ350 Rental Generator Set, and CX31-P600-C13I Petroleum Power Train Package platforms. Designed as a direct replacement injector, it matches the factory fuel injection specifications required by the C13 common rail / electronic fuel injection system, supporting reliable cold starting, stable idle quality, and consistent power output under varying load conditions. This injector is intended for engine rebuild projects, scheduled maintenance, and field service replacement where OEM-equivalent performance is required.

Manufactured with heavy-duty construction, precision-machined nozzle components, and engineered sealing surfaces, the 348-4090 injector provides fine fuel atomization and accurate fuel delivery that promotes improved combustion, reduced exhaust smoke, and restored engine performance. It is suitable for excavators including E345C and E349D, stationary power systems, mining equipment, oil and gas power systems, heavy-duty truck engines, and emergency generator applications. All fitment must be confirmed by engine serial number to ensure proper application within the C13 engine family.

To maintain long service life, operators should use clean diesel fuel, replace fuel filters on schedule, drain the water separator regularly, and keep the air intake system free of contamination. Common signs of injector failure include hard starting, rough idle, black or white smoke, high fuel consumption, engine misfire, knocking, and reduced power. Professional diagnosis using ECM scanning, fuel pressure testing, cylinder balance testing, return rate testing, and test bench verification is recommended prior to replacement. For best results, injectors should be installed as a matched set by qualified technicians.
