Hyundai Elantra: Fuel Delivery System / Delivery Pipe
Repair procedures
•
| 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. | 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 battery negative (-) cable. •
| When removing the fuel pump fuse, a Diagnostic Trouble Code (DTC) may occur. Delete the code with the diagnostic tool after completion of "Release Residual Pressure in Fuel Line" work. |
|
|
3. | Remove the intake manifold. (Refer to Engine Mechanical System - "Intake Manifold") |
4. | Use the special service tool [SST No. : 09314-3Q100 or 09314-27130] to remove the high pressure fuel pipe function block mounting bolt (A) and removing the flange nut (B). Tightening Torque : Function block mounting bolt : 9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 lb-ft) Flange nut : 29.4 - 35.3 N.m (3.0 - 3.6 kgf.m, 21.7 - 26.0 lb-ft) |

|
5. | Remove the installation bolt (A), and then remove the delivery pipe and injector assembly (B). Tightening Torque : 18.6 - 23.5 N.m (1.9 - 2.4 kgf.m, 13.7 - 17.4 lb-ft) |

|
6. | Disconnect the injector & rail pressure sensor connector (A). |
7. | Remove the fixing clip (A), and then separate the injector from the delivery pipe 
|
1. | Install in the reverse order of removal. •
| Do not reuse the high pressure fuel pipe. |
•
| Be careful not to deform the shape of the high pressure fuel pipe. |
•
| Do not tilt the torque wrench when tightening the nut. |
•
| Install the component to the specified torques. |
•
| Check the fuel leakage after installing the high pressure fuel pipe. |
•
| Use the special service tool [SST No. : 09314-3Q100 or 09314-27130] to install the high pressure fuel pipe. |
|
•
| Do not reuse the mounting bolt. |
•
| Do not reuse the injector fixed clip. |
•
| Do not reuse the combustion seal (A). 
|
•
| Be careful not to apply oil to the combustion seal. |
•
| Do not reuse the O-ring (A), support disc (B), rubber washer (C). 
|
•
| When replacing the rubber washer, the steal plate part should be faced the cylinder installation part and the rubber plate part should be faced the injector body part. |
•
| Apply engine oil to the injector O-ring. |
•
| When inserting the injector, be careful not to damage the injector tip |
•
| Do not reuse the high fuel pipe. |

Description
DescriptionThe auto defogging sensor is installed on the front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging. The air conditioner control module receives signal from the sensor and restrains moisture and eliminate defog by controlling the intake actuator, A/C, auto defogging actuator, blower motor rpm, and mode actuator...
