Fuel line

Repair Procedures

Removal

Be careful not to damage the fuel line during repair.

When removing the high-pressure fuel pump, the fuel tube, delivery pipe and injector may be injured due to high-pressure fuel leakage. Do not perform any repair work immediately after stopping the engine.

High-Pressure Fuel Tube [High-Pressure Fuel Pump ↔ Delivery Pipe]

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 control wiring harness (A).

   

4. 4
   Remove the high-pressure fuel line mounting bolts (A). High-pressure fuel line mounting bolt: 9.8–11.8 N·m

   

   

5. 5
   Remove the high-pressure fuel line flange nut (B). High-pressure fuel line flange nut: 29.4–35 N·m

   Use the Special Service Tool [SST No.: 09314-3V100] to install the high-pressure fuel line and adapter tube.

   

   

6. 6
   Remove the high-pressure fuel hose (A).

   

7. 7
   Release the residual fuel pressure in the fuel line. (Refer to Fuel System - "Release Residual Fuel Pressure in Line")
8. 8
   Turn the ignition switch OFF and disconnect the negative (-) battery terminal.
9. 9
   Remove the air cleaner assembly. (Refer to Engine Mechanical System - "Air Cleaner")
10. 10
    Remove the coolant reservoir. (Refer to Engine Mechanical System - Coolant Reservoir)
11. 11
    Remove the intake manifold. (Refer to Engine Mechanical System - "Intake Manifold")
12. 12
    Remove the high-pressure fuel line cross flange nut (A). Cross flange nut of high-pressure fuel line: 29.4–35 N·m

    

13. 13
    Release the residual fuel pressure in the fuel line. (Refer to Fuel System - "Release Residual Fuel Pressure in Line")
14. 14
    Turn the ignition switch OFF and disconnect the negative (-) battery terminal.
15. 15
    Remove the control wiring harness (A).

    

16. 16
    Remove the fuel line mounting bolts (A).
17. 17
    Remove the low-pressure fuel line mounting nuts (B).

    

18. 18
    Remove the low-pressure fuel line (A).

    

19. 19
    Release the residual fuel pressure in the fuel line. (Refer to Fuel System - "Release Residual Fuel Pressure in Line")
20. 20
    Turn the ignition switch OFF and disconnect the negative (-) battery terminal.
21. 21
    Remove the air cleaner assembly. (Refer to Engine Mechanical System - "Air Cleaner")
22. 22
    Remove the lower fuel line (A) after loosening the mounting nuts.
23. 23
    Disconnect the vapor hose (B). Lower fuel line mounting nut: 3.9–5.9 N·m

    

24. 24
    Remove the fuel line bracket (A).

    

25. 25
    Raise the vehicle.
26. 26
    Remove the fuel line bracket (A).

    

27. 27
    Remove the fuel tank. (Refer to Fuel System - "Fuel Tank")
28. 28
    Open the vapor tube and the fuel line retaining clip (A) using a screwdriver.

    

    

    

High-Pressure Fuel Line [Delivery Pipe (Bank 1) Line ↔ Delivery Pipe (Bank 2) Line] Low-Pressure Fuel Line [High-Pressure Fuel Pump ↔ Extension Fuel Line] Low-Pressure Fuel Line [Fuel Tank <-> Extension Fuel Line]

Installation

1. Install in the reverse order of removal.

Inspection

1. Visually inspect the fuel lines for cracks, leaks, loose connections, deformation, or fuel tank strap loosening.
