REMOVAL

CAUTION

Be careful not to drop the fuel injector when the 
delivery pipe is removed.
The delivery pipe must be removed with the fuel 
injector, fuel return pipe and fuel pressure regulator 
attached.

INSTALLATION SERVICE POINT

HOSE INSTALLATION

CAUTION

Do not let the engine oil get into the delivery 
pipe, or it will be damaged.
1. Apply a drop of new engine oil to the O-ring.
2. Turn the fuel high-pressure hose to the right and 

left to install to the delivery pipe.

Be careful not to damage the O-ring. After 
installing, check that the fuel high-pressure hose 
turns smoothly.

3. If the fuel high-pressure hose does not turn 

smoothly, the O-ring may be trapped. Remove the 
fuel high-pressure hose, re-install the fuel 
high-pressure hose into the delivery pipe and 
check again.

4. Tighten the fuel high-pressure hose to the 

specified torque.

Tightening torque: 5.0 

± 1.0 N⋅m
