original 348-4090 Diesel Fuel Injector Assembly for C13 Engine Excavator E345C E349D Common Rail Fuel Injector 3484090 332-1419 20R-2437 Engineering Machinery Parts original new injector

Engineered for demanding industrial duty cycles, the 348-4090 C13 diesel fuel injector delivers factory-level fuel metering performance to C13-powered platforms operating in construction, power generation, and petroleum service environments. Public catalog data associates this Injector GP-Fuel (OE 348-4090 / 3484090) with the C13 Industrial Engine, the C13 XQ350 Rental Generator Set, and the CX31-P600-C13I Petroleum Power Train Package. The unit is also cross-referenced under 332-1419, 292-3666, 232-1198, 239-4908, 249-0705, 249-0713, 253-0608, 250-1309, 294-3002, 10R-7236, 10R-3262, 10R-1274, 10R-2977, 20R-8045, 20R-8046, 20R-2437, 359-4080, and 359-4090 for broad global sourcing compatibility.

Key engineering features include heavy-duty construction, precision fuel delivery, fine spray atomization, engineered sealing surfaces, and direct-replacement geometry that matches OE mounting and electrical interfaces. Supplier testing options and multi-number searchability make the injector suitable for B2B distribution, fleet rebuild programs, and workshop inventory. Every unit is shipped in protective industrial packaging to safeguard nozzle and control valve integrity during transit and long-term storage.

To maximize service life, operators should use clean diesel fuel, service fuel filters and water separators on schedule, maintain engine oil quality, and diagnose faults such as hard starting, rough idle, black or white smoke, misfire, low power, or fault codes with ECM scanning, cylinder balance, return-flow, and test bench verification. Applications like E345C and E349D excavators must be confirmed by engine serial number and old injector number before purchase.
