"
FUEL PUMP PROTECTOR REMOVAL
Lift up the transmission with a jack to create clearance between
the engine and the front deck, and remove the fuel pump
protector.

"
DELIVERY PIPE, INJECTOR AND FUEL
PRESSURE REGULATOR ASSEMBLY REMOVAL
Remove the delivery pipe (with the injectors and fuel pressure
regulator attached to it).
Caution
Care must be taken, when removing the delivery pipe,
not to drop the injector.
INSTALLATION SERVICE POINT
"
A
A
HIGH-PRESSURE FUEL HOSE INSTALLATION
1.
When connecting the high-pressure fuel hose to the
delivery pipe, apply a small amount of new engine oil
to the O-ring and then insert the high-pressure fuel hose,
being careful not to damage the O-ring.
Caution
Be careful not to let any engine oil get into the delivery
pipe.
2.
While turning the high-pressure fuel hose to the left and
right, install it to the delivery pipe.
3.
Check to be sure that the high-pressure fuel hose turns
smoothly.
If it does not turn smoothly, the O-ring may be trapped,
remove the high-pressure fuel hose and then re-insert
it into the delivery pipe and check once again.
INSPECTION
Check the following points; replace the part if a problem is
found.
INTAKE MANIFOLD CHECK
1.
Check for damage or cracking of any part.
2.
Check for obstruction of the negative pressure (vacuum)
outlet port, and for obstruction of the water passage or
gas passage.
3.
Using a straight edge and thickness gauge, check for
distortion of the cylinder head installation surface.
Standard value: 0.15 mm or less
Limit: 0.20 mm
