In case of removing the high pressure fuel pump, high
pressure fuel pipe, delivery pipe, and injector, there may be injury
caused by leakage of the high pressure fuel. So don’t do any repair
work right after engine stops.
1.
Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2.
Release the residual pressure in fuel line (Refer to the Fuel
Delivery System - Repair Procedures - "Release Residual Pressure in
Fuel Line").
When removing the fuel pump relay, a Diagnostic Trouble Code
(DTC) may occur. Delete the code with the GDS after completion of
“Release Residual Pressure in Fuel Line” work.
3.
Remove the intake manifold (Refer to "Intake And Exhaust System" in EM group).
4.
Disconnect the injector connectors (A) and the rail pressure sensor connector (B).
5.
Remove the high pressure fuel pipe (C).
6.
Remove the installation bolt (D), and then remove the delivery pipe and injector assembly from the engine.
Installation
•
Install the component with the specified torques.
•
Apply engine oil to the injector O-ring.
•
Do not use already used injector O-ring again.
•
Do not reuse the bolts.
•
When insert the injector, be careful not to damage the injector tip.
•
Use proper tooling for change of combustion seal. Take proper precautions not to damage surface during assembly or disassembly.
•
Avoid dropping the fuel pipe (including injectors) or bumping
it into any hard objects sincedamage to the internal components may
occur. If necessary, visually inspect and confirmproper operation with
performance tests prior to reuse.
•
Before installing the injector into the cylinder head, clean
the injector hole and avoidcontaminants from entering inside the
injector hole. When installing the injector, avoid bumpingthe injector
tip into any of the surrounding components since the tip may become
damagedfrom the impact.
•
When fastening the three fuel delivery pipemounting bolts, fully hand-tighten first, andthen tighten in the proper sequence ( > > )
in several cycles up tothe specified torque. The delivery pipeshould
move less than 1/8 inch (approx.3mm), whenever each bolt is tightened.
