Notice:
- Always use new O-rings.
- When checking the injectors, do not allow any foreign material to enter or adhere to the injectors, fuel rails, or O-rings.
- Be careful not to twist or pinch the Orings when installing the injectors.
- If an injector is subject to strong shocks or excessive force, replace it.
- If installing the original fuel rails and bolts, remove the white paint marks using a cleaning solvent. Otherwise, paint chips on the bolt seats could prevent the bolts from being tightened to the specified torque.
1. Install a new seal onto the end of each injector.
2. Install the injectors "1" to the fuel rails "2".
3. Install the primary injector joint "3", making sure to install them in the correct direction.
4. Install the injector assemblies to the throttle bodies.
5. Check the injector pressure after the injectors are installed to the throttle bodies. Refer to "Checking the injector pressure".
