Hyundai Santa Cruz: Fuel Delivery System / Delivery Pipe

- Removal Low Pressure Delivery Pipe

1. Release the residual pressure in fuel line. (Refer to Fuel Delivery System - "Release Residual Pressure in Fuel Line")

2.Turn the ignition switch OFF and disconnect the negative (-) battery terminal.

3.Remove the engine cover.(Refer to Engine Mechanical System - "Engine Cover")

4.Disconnect the injector connector (A).

5.Disconnect the fuel feed quick-connecotrs (A).

6.Remove the delivery pipe mounting bolts (A).

Tightening torque :18.7 - 23.5 N·m (1.9 - 2.4 kgf·m, 13.8 - 17.3 lb·ft)

• Open the clamp cover (A) before disconnect the quick connector. (If the clip is applied)

• When removing the quick-connnector with the clip removing tool (A), be careful not to damage the plastic clip (B).

• If the clip is damaged, it can cause a fuel leak due to bad connection and could result in a fire.

7.Remove injector from the delivery pipe (A) by opening the fixing clip on either side.

1. Release the residual pressure in fuel line. (Refer to Fuel Delivery System - "Release Residual Pressure in Fuel Line")

2.Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

3.Remove the engine cover.(Refer to Engine Mechanical System - "Engine Cover")

4.Disconnect the ignition coil connector (A).

5.Remove the head cover foam (B).

6.Remove the high pressure pump foam (A).

7.Remove the air cleaner assembly.(Refer to Engine Mechanical System - "Air Cleaner")

8.Remove the intercooler inlet hose.(Refer to Engine Mechanical System - "Intercooler")

9.Loosen the high pressure fuel pipe flange nut (A, B) using the SST (09314-L1100).

12.Remove the injector foam (A).

13. Remove the high pressure fuel pipe flange nut (A).

14. Remove the delivery pipe & injector assembly after loosening the mounting bolts (B).

Tightening torqueA : 29.4 - 35.3 N.m (3.0 - 3.6 kgf.m, 21.7 - 26.0 lb-ft)B : 18.7 - 23.5 N·m (1.9 - 2.4 kgf·m, 13.8 - 17.3 lb·ft)

15. Disconnect the injector & rail pressure sensor connectors (A).

16. Remove injector from the delivery pipe (A) by opening the fixing clip on either side.

1.Install in the reverse order of removal.

• Use the spaner torque wrench (27mm) to install the high pressure fuel pipe.

• Do not reuse the high pressure fuel pipe.

• Be careful not to transform the shape of the high pressure fuel pipe.

• Torque wrench should not be tilt when you tighten the nut.

• Follow the order and the tightening torque when you assemble.

• Inspect fuel leakage after high pressure fuel pipe assembly.
