Delivery Pipe Repair Procedures

Removal

When removing the high pressure fuel pump, high pressure fuel line, delivery pipe and injector, injury may occur due to high pressure fuel leakage. Do not perform repairs immediately after stopping the engine.

1. 1
   Turn the ignition switch OFF and disconnect the negative (-) battery cable.
2. 2
   Release the fuel line residual pressure. (Refer to Fuel System - "Release Fuel Line Residual Pressure")

   A diagnostic trouble code (DTC) may be set when the fuel pump relay is removed. Clear the DTC with GDS after performing "Relieve Residual Fuel Pressure".

3. 3
   Disconnect the injector connectors (A, B).

   

4. 4
   Remove the intake manifold. (Refer to Engine Mechanical System - "Intake and Exhaust System")
5. 5
   Remove the high pressure fuel tube.

   1. Remove the bracket mounting bolt (A).

      

   2. Remove the high pressure pipe flange nut (A, B) in the order of A and B using the special service tool [SST No.: 09314-3V100].
   3. Remove the high-pressure fuel pipe bracket bolt (C).

      

      

6. 6
   Remove the delivery pipe and injector assembly from the engine by removing the mounting bolt (A).

   

   

Installation

Do not reuse the injector retainer.

Install the component with the specified torque. Be careful not to drop the component, as internal damage may occur. If dropped, 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 bolt.

When inserting the injector, be careful not to damage the injector tip.

1. To install, reverse the removal procedure. Delivery pipe bolt: 18.6 ~ 24 N·m High pressure fuel line nut: 29.4 ~ 35 N·m
