Engineered for demanding Cummins 15L platforms, this diesel fuel injector carries primary OE number 49548884 and delivers precise fuel metering for QSK15, QSKX15, QSX15, ISX15 and X15 engines. Built to an original type standard, it supports fine atomization and accurate fuel delivery across high-load industrial, generator, mining and heavy-duty truck applications.
With strong cross-reference coverage to 4928262 and related alternatives including 4928262NX, 4928262PX, 4928262RX, 1731091, 1499714, 570016, 1521977, 1481827, 4088723, 1846351, 4088301 and 4062569, this injector simplifies sourcing for distributors and service teams. It supports stable idle, power recovery and reduced smoke potential, and is suited to repair-shop workflows with optional full-set supply, testing support and global aftermarket availability. Exact compatibility must be confirmed by engine serial number, CPL and removed injector number.
For reliable service life in high-load Cummins 15L applications, use clean diesel fuel, replace fuel filters on time, drain the water separator and keep the fuel tank and lines clean. When symptoms such as hard starting, rough idle, black or white smoke, power loss or high fuel consumption appear, diagnosis should include fuel pressure testing, return-flow testing, ECM fault-code reading, cylinder cut-out testing and visual inspection to confirm injector condition before replacement.
