Sourcing the correct injector for a QSK19 engine starts with the number, and Y431K05248 is the primary OE reference for this common rail diesel fuel injector. Cross-checked with Y431K05417, 4964171, and Y431K05558, this part is engineered for the Cummins QSK19-Series 19 L inline 6-cylinder engine equipped with Modular Common Rail Fuel System (MCRS) technology and integrated electronic controls. Format variants Y 431 K05 248 and Y-431-K05-248 all identify the same component.
Designed for high-pressure fuel delivery, accurate metering, and stable atomization, this injector supports cylinder balance, reduced smoke, improved starting, and restored engine power when correctly matched and installed. It serves QSK19 G-Drive, Rail, Marine, Oil & Gas, and MCRS applications across power generation, mining, marine, rail, oilfield, and construction markets, making it suitable for diesel repair shops, generator service companies, mining fleets, engine rebuilders, and parts distributors.
For reliable performance, use clean diesel fuel, replace fuel filters, drain water separators, and store injectors in sealed packaging to avoid nozzle damage. During service, check ECM fault codes, injector return flow, cylinder contribution, connector condition, and fuel pressure. For high-hour QSK19 engines, matched-set testing or replacement may reduce repeat downtime and cylinder imbalance, protecting overall fuel-system life.
