Engineered specifically for the Cummins QSK19-Series platform, the Y431K05248 common rail diesel fuel injector supports the 19 L inline 6-cylinder engine across G-Drive, Rail, Marine, Oil & Gas, and MCRS configurations. QSK19 G-Drive versions are listed at 500–550 kW prime and 550–600 kW standby, marine versions at 500–800 hp, and oil and gas versions at 525–800 hp. This injector is cross-referenced with Y431K05417, 4964171, and Y431K05558, making sourcing straightforward for engine rebuilders and parts distributors.
Built for the Modular Common Rail Fuel System (MCRS), this injector delivers high-pressure fuel delivery, accurate metering, and stable atomization when correctly matched and installed. Proper fitment supports cylinder balance, reduced smoke, improved starting, and restored engine power. It is suited to diesel repair shops, generator service companies, mining fleets, marine service suppliers, rail maintenance teams, and oilfield service companies working on QSK19-powered equipment.
For reliable service life, use clean diesel fuel, replace fuel filters, drain water separators, and prevent fuel tank contamination. During diagnosis of hard starting, rough idle, black or white smoke, misfire, low power, or injector fault codes, perform return flow testing, rail pressure testing, ECM scanning, cylinder cut-out testing, and nozzle inspection. For high-hour QSK19 engines, matched-set testing or replacement may reduce repeat downtime and cylinder imbalance.
