Installation Guide

1. Safety First: Relieve all pressure from the fuel system and disconnect the negative battery terminal before beginning.
2. Access the Fuel Rail: Remove any components blocking access to the fuel rail and injectors.
3. Disconnect Injectors: Carefully unplug the electrical connector from each fuel injector you are replacing.
4. Remove Fuel Rail: Unbolt the fuel rail from the intake manifold. Gently rock or pull the rail to release the injectors from their ports.
5. Remove Old Injectors: Pull the old injectors straight out from the fuel rail. Remove and discard the old O-rings and grommets.
6. Prepare for Installation: Clean the injector ports on the intake manifold and the mounting points on the fuel rail to ensure a clean sealing surface.
7. Install New Injectors: Lightly lubricate the new O-rings with clean engine oil. Press the new injectors firmly into the fuel rail until they seat correctly.
8. Reinstall Fuel Rail: Carefully place the fuel rail and new injectors back into the intake manifold ports. Tighten the mounting bolts to the manufacturer's recommended torque specification.
9. Reconnect Components: Reattach the electrical connectors to each new injector.
10. Final Checks: Reconnect the battery terminal. Turn the ignition key to the 'On' position (without starting the engine) to prime the fuel system. Inspect for any fuel leaks around the injectors and fuel rail.
11. Start Engine: Once you've confirmed there are no leaks, start the engine and check for smooth operation.
