Kia Rio: High Pressure Fuel Pump Removal - Fuel Delivery System - Engine Control / Fuel System - Kia Rio UB 2012-2024 Service ManualKia Rio: High Pressure Fuel Pump Removal


     
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. Before repairing the high pressure system, be sure to release the residual pressure in fuel line as step 2 in below procedure.
1.
Turn the ignition switch OFF and disconnect the battery negative (-) cable.
2.
Release the residual pressure in fuel line (Refer to the Fuel Delivery System - Repair Procedures - "Release Residual Pressure in Fuel Line").

     
When removing the fuel pump relay, a Diagnostic Trouble Code (DTC) may occur.
Delete the code with the GDS after completion of “Release Residual Pressure in Fuel Line” work.
3.
Remove the air cleaner and the air intake hose (Refer to “Intake And Exhaust System” in EM group).
4.
Disconnect the fuel pressure regulator valve connector (A).
5.
Disconnect the fuel feed tube quick-connector (B).


6.
Remove the high pressure fuel pipe.
(1)
Remove the installation nut (A) from the high pressure fuel pump with the special service tool [SST No.: 09314-3Q100 or 09314-27130]


(2)
Remove the installation nut (B) from the delivery pipe with the special service tool [SST No.: 09314-3Q100 or 09314-27130]


(3)
Disconnect the engine coolant temperature sensor connector.
(4)
Remove the function block (C), and then remove the high pressure fuel pipe.


7.
Remove the installation bolts (D), and then remove the high pressure fuel pump from the cylinder head assembly.

     
Unscrew in turn the two bolts in small step (0.5 turns). In case of fully unscrewing one of the two bolts with the other bolt installed, the housing surface of the cylinder head may be broken because of tension of the pump spring.
