Installation Notes and Tips

Replace injector seals during service, since the manufacturer notes they are single-use items. Inspect the injector bore, fuel rail connection, and electrical connector before installation. Confirm the vehicle’s engine code and build date against the fitment notes, especially for the 2004 Nissan Murano from 10/2003 and the 2004 Infiniti FX35 with Unisia Jecs unit.

Because this is a fuel system component, clean handling and proper sealing are important to prevent leaks and drivability complaints after installation.
