Warning
-
• Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying.
-
― Fuel may cause irritation if it comes in contact with skin and eyes.
― If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.
• A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before performing work on the fuel system, discharge static electricity by touching the vehicle body.
-
Caution
-
• Do not disassemble the high pressure fuel pump.
• Do not damage the sealing surface or the lock part of the fuel pipe.
• Damage or deformation to the end of the high pressure line pipe may cause fuel leakage.
• Disconnecting/connecting the quick release connector without cleaning it may cause damage to the fuel pipe and quick release connector. Always clean the quick release connector joint area before disconnecting/connecting using a cloth or soft brush, and make sure that it is free of foreign material.

4. Remove the air cleaner and air hose as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
5. Disconnect the harness clip as shown in the figure.
6. Disconnect the hoses as shown in the figure.
7. Disconnect the following parts connectors.
-
• Purge solenoid valve

8. Remove the purge solenoid valve and catch tank and purge solenoid valve bracket as a single unit. (See PURGE SOLENOID VALVE REMOVAL/INSTALLATION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
9. Remove in the order indicated in the table.
-
Note
-
• Only when the high pressure fuel pump (figure (4)) is removed, the rear housing (figure (8)) does not have to be removed.
10. Install in the reverse order of removal.
11. Complete the “AFTER SERVICE PRECAUTION”. (See AFTER SERVICE PRECAUTION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

High Pressure Fuel Pipe Removal Note
-
Caution
-
• When removing the high pressure fuel pipe, the end of the high pressure fuel pipe may be damaged because the clearance between the high pressure fuel pump and the high pressure fuel pipe is small. Be very careful when handling the end of the high pressure fuel pipe so as not to damage it.
• If the high pressure fuel pump is removed with the high pressure fuel pipe installed, the high pressure fuel pipe and fuel distributor may be damaged because of the excessive force caused by the spring force of the high pressure fuel pump. The high pressure fuel pipe and fuel distributor must be replaced if they are damaged. Always remove the high pressure fuel pipe before removing the high pressure fuel pump.
1. Remove the high pressure fuel pipe.
Rear Housing Removal Note (Without coolant control valve)
1. Remove the vacuum pump. (See VACUUM PUMP REMOVAL/INSTALLATION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
2. Remove the rear housing.
Rear Housing Removal Note (With coolant control valve)
1. Remove the vacuum pump. (See VACUUM PUMP REMOVAL/INSTALLATION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
2. Disconnect the hose clips shown in the figure.
3. Remove the bracket shown in the figure.
4. Disconnect the exhaust CMP sensor connector.
5. Remove the bolts shown in the figure and set the bracket aside so that it does not interfere with the servicing.
6. Remove the rear housing.

Caution
-
• Damage or deformation to the end of the high pressure fuel pipe may cause fuel leakage. When installing the high pressure fuel pipe to the high pressure fuel pump, be very careful while handling the end of the high pressure fuel pipe.
• If parts are exposed to fuel, their function may be decreased or a fire may occur. Always wipe off any leaked fuel using a clean rag.
• Do not let foreign materials enter into the high pressure fuel pipe.
• Install a new high pressure fuel pipe because it cannot be reused.
