The LDFN1696 Diesel Fuel Injector Nozzle from SRT Automotive (formerly Lucas Diesel Systems) is a new aftermarket replacement component designed for compatible Ford® 7.3L Power Stroke and Navistar® T444E HEUI diesel fuel injectors.
Designed for professional injector rebuilding and repair, the LDFN1696 is listed by the supplier for AA, AB, AC, AD, AE, and AF injector configurations. The nozzle forms part of the injector's fuel-delivery system, directing atomized diesel fuel into the combustion chamber according to the injector's operating and calibration requirements.
This replacement nozzle is intended for professional fuel-injection service, injector rebuilding, remanufacturing, and component replacement in compatible light-duty and medium-duty diesel applications.
Important: This listing is for one fuel injector nozzle, not a complete fuel injector or nozzle assembly unless otherwise specified. Verify the original injector identification code, nozzle configuration, and engine application before ordering.
