CAUTION: The fuel rail bolts are actually lower intake manifold bolts. These bolts must be torqued in a mandatory torque sequence.
- Insert fuel injector nozzles into openings in the cylinder heads. Seat the injectors in place. Install the fuel rail bolts and tighten bolts in a mandatory torque sequence to 28 N.m (20.5 ft. lbs.).
- Correctly position and connect the fuel injector electrical harness connectors to the fuel injectors.
CAUTION: Make sure the fuel line quick connector is connected properly. Failure to connect the fuel line correctly may result in a fuel leak at the rail assembly. Fuel leaked onto a hot engine may ignite resulting in damage to the vehicle.
