When removing the high pressure fuel pump, high pressure fuel
pipe, delivery pipe, and injector, injury may be caused by leakage of
high pressure fuel. For this reason, do not attempt any repairing
immediately after engine stops.
1.
Release the residual pressure in fuel line.
(Refer to the Fuel Delivery System - Repair Procedures - "Release Residual Pressure in Fuel Line")
2.
Turn the ignition switch OFF and disconnect the battery negative (-) terminal.
3.
Remove the high pressure fuel fump foam (A).
4.
Disconnect the fuel pressure control valve connector (A) and fuel feed tube quick-connector (B).
5.
Remove the intake manifold.
(Refer to Engine Mechanical System - "Intake Manifold")
6.
Remove the high pressure fuel pipe.
(Refer to Fuel Delivery System - "Fuel Line")
7.
Remove the mounting bolts (A), and then remove the high pressure fuel pump (B) from the cylinder head assembly
Unscrew in turns the two bolts in small steps (0.5 turns).
When one of the two bolts is fully unscrewed while the other bolt still
intact, the housing surface of the cylinder head may be broken due to
tension of the pump spring.
Installation
•
Be sure that the low pressure fuel hose quick-connector (A)
is completely connected to the high pressure fuel pump by the locking
sound.
•
Double-check the complete connection of the low pressure fuel
hose to the high pressure fuel pump by pulling it after connecting.
•
Be sure to install the high pressure fuel pipe (B) to the specified torques.
•
Because fuel leak may cause fire, thoroughly inspect leakage of all fuel line connection parts at engine start condition.
•
Before installing the high pressure fuel pump, position the
roller tappet in the lowest position by rotating the crankshaft.
Otherwise the installation bolts may be broken because of tension of the
pump spring.
•
Do not reuse the used bolt.
•
Do not reuse the used high pressure fuel pipe.
•
When tightening the installation bolts of the high pressure
fuel pump, tighten in turns the bolts in small steps (0.5 turns) after
tightening them to hand-screwed torque.
•
Install the component with the specified torques.
•
First hand-tighten the fasteners fully until they are not
fastened any more in order to have them inserted in place and then
completely tighten to the specified torque using a torque wrench.
Bolts or nuts not tightened in a straight line with the
matching bolt holes or fittings may cause fuel leakage due to broken
threads.
•
Note that internal damage may occur when the component is dropped. In this case, use it after inspecting.
•
Apply engine oil to the O-ring (A) of the high pressure fuel
pump, the roller tappet (B), and the protrusion (C). Also apply engine
oil to the groove on the location where the protrusion (C) is installed.
1.
Install in the reverse order of removal.
Use the special service tool [SST No.: 09314-3V100] to install the high pressure fuel pipe.
Inspection
Visually check the fuel lines for cracks, leakage, loose connections, deformation or tank band looseness.Removal
