Pipe Delivery

Repair Procedures

Removal

When removing the high-pressure fuel pump, high-pressure fuel line, delivery pipe, and injector, fuel leakage may cause injury from high-pressure fuel. For this reason, do not attempt repair immediately after stopping the engine.

1. 1
   Release the residual fuel pressure in the fuel line. (Refer to Fuel System - "Release Residual Fuel Pressure in Line")
2. 2
   Turn the ignition switch OFF and disconnect the negative (-) battery terminal.
3. 3
   Remove the air cleaner assembly. (Refer to Engine Mechanical System - "Air Cleaner")
4. 4
   Remove the coolant reservoir. (Refer to Engine Mechanical System - Coolant Reservoir)
5. 5
   Remove the intake manifold. (Refer to Engine Mechanical System - "Intake Manifold")
6. 6
   Remove the adapter fuel tube (A). Cross flange nut of high-pressure fuel line: 29.4–35 N·m

   

7. 7
   Remove the mounting bolts (A), then remove the delivery pipe and injector assembly from the engine. Delivery pipe assembly mounting bolt: 18.6–24 N·m

   

Installation

Do not reuse the injector retainer. Install the component to the specified torque. Note that internal damage may occur if the component is dropped. In this case, inspect it before use. Apply engine oil to the O-ring of the injector. Do not reuse the injector O-ring. Do not reuse the bolts. When installing the injector, be careful not to damage the injector tip.

Use the Special Service Tool [SST No.: OK353-F6100] to install the high-pressure fuel tube and adapter tube.

1. Install in the reverse order of removal.
