To reinstall the fuel injectors, follow the reverse order of removal steps. Make sure to properly tighten the fuel rail mounting bolts.

For 2GR-FKS V6 models, there are specific instructions depending on whether it is port injection or direct injection fuel rails. For port injection, you need to remove the upper intake manifold, disconnect the fuel lines and electrical connectors, and remove the fuel rail and injectors as a single assembly. For direct injection, you need to remove the upper intake manifold and high-pressure fuel pump, disconnect the fuel lines and electrical connectors, and then remove the fuel rail and injectors.

Twist and pull the injectors to remove them from the fuel rail and store them in a labeled container.
