Built for demanding fuel injection service, the Cummins 1764365 unit injector delivers precise fuel metering and fine atomization across heavy-duty diesel applications. It is positioned as a Cummins and Scania cross-reference product, indexed under Cummins QSK15, QSKX15, QSX15, ISX15 and X15 inquiry-matching categories, with strong public association to Scania HPI Gen 3, DC12.14 and R420 platforms. The Cummins QSX15 is a 15-liter, 6-cylinder engine rated at 500–675 hp and 1650–2050 lb-ft torque.

This injector supports stable idle, power recovery and reduced smoke potential while providing broad repair-market coverage. Extensive cross-reference value is offered through alternative numbers including 579261, 4954646, 570016, 4903028, 4076963, 1481827, 1521978, 1511696, 579263, 1499257, 1521977, 1846349, 4076912, 1473430 and 3331153. Optional testing support and global aftermarket supply flexibility make it suitable for truck, excavator, generator, mining and industrial diesel service channels.

For reliable service life, use clean diesel fuel, replace fuel filters on time, drain the water separator and keep the tank and fuel lines clean. Reference QSX15 intervals include oil, filter and fuel filter service at 500 hours, but exact maintenance must follow the correct engine manual and duty cycle. When issues such as hard starting, rough idle or power loss occur, diagnose with fuel pressure testing, return-flow testing, ECM fault-code reading, cylinder cut-out testing and visual inspection.
