- Apply a small amount of engine oil to each fuel injector O-ring. This will help in the fuel rail installation.
- Position the fuel rail assembly while aligning the injectors into the machined holes in the intake manifold.
- Guide each injector into the intake manifold using care not to tear the injector O-rings.
- Using a side to side motion, gently rock the left fuel rail while pushing down until all four left side fuel injectors have completely seated into the machined holes in the intake manifold.
- Using a side to side motion, gently rock the right fuel rail while pushing down until all four right side fuel injectors have completely seated into the machined holes in the intake manifold.
- Install the four fuel rail mounting bolts (4) and tighten to 11 N.m (8 ft. lbs.).
- Connect the make up air hose (3).
