CAUTION

• Do not kink the fuel high-pressure hose as it is made of 

plastics.

• Do not let the engine oil get into the fuel rail.

1. Apply a drop of new engine oil to the O-ring.
2. Turn the fuel injector to the right and left to install to the fuel 

rail. Repeat for fuel damper and fuel high-pressure hose. Be 
careful not to damage the O-ring. After installing, check that 
they turn smoothly.

3. If some of them dose not turn smoothly, the O-ring may be 

trapped, remove it, re-install it into the fuel rail and check 
again.

4. Tighten the fuel high-pressure hose to the specified torque.
