REMOVAL SERVICE POINT
<<A>> DELIVERY PIPE, FUEL INJEC-
TOR, FUEL RETURN PIPE AND FUEL
PRESSURE REGULATOR ASSEMBLY
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
>>A<< O-RING/ FUEL HIGH-PRESSURE
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
INSPECTION
M1151003100694
Check the following points; replace the part if a prob-
lem is found.
Inlet Manifold Check
1. Check for damage or cracking of any part.
2. Clogging of the negative pressure (vacuum) outlet
port, or clogging of the exhaust gas recirculation
passages.
3. Using a straight edge and feeler gauge, check for
distortion of the cylinder head installation surface.
Standard value: 0.15 mm or less
Limit: 0.20 mm
