PARTS DESCRIPTION
Product Overview
A diesel injector must deliver fuel at the correct moment and in the intended spray pattern for its fuel system. Replacing an injector therefore requires more than matching the engine name alone; the injector number and system version should also be checked.
The 4493315 Fuel Injector is supplied as a replacement solution for confirmed Cummins diesel engine applications. Selection should be based on the engine specification and reference information, especially when more than one version exists.

Why This Part Matters
Injector design can differ by nozzle configuration, control type, calibration, connector, and fuel-system generation. Even engines sharing the same model designation may use different injector numbers. Correct matching helps maintain the intended injection process and avoids fitment or calibration problems during engine repair.
For common-rail and electronically controlled systems, the visible engine model alone may not identify the correct injector. markings, connector details, and the complete injector number provide a more reliable basis for matching.
