Hyundai Palisade: Fuel Delivery System / High Pressure Fuel Pump
Repair procedures
| 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 high pressure fuel pump foam (A).
|
| 4. |
Remove the control wiring harness (A).
|
| 5. |
Remove the fuel line mounting bolts (A).
|
| 6. |
Disconnect the high pressure fuel control valve connector (A) and low
pressure fuel feed tube quick-connector (B).
|
| 7. |
Remove the high pressure fuel pipe.
(Refer to Fuel Delivery System - "Fuel Line")
|
| 8. |
Remove the mounting bolts (A), and then remove the high pressure fuel
pump (B) from the cylinder head assembly.
|
High pressure fuel pump mounting bolt :
12.8 - 14.7 N.m (1.3 - 1.5 kgf.m, 9.4 - 10.9 lb-ft)
|
| •
|
Unscrew in turns the two bolts in small steps (0.5 turns).
When one of the two bolts is fully unscrewed while the
other bolt still intact, the housing surface of the
cylinder head may be broken due to tension of the pump
spring.
|
|
|
| • |
Be sure that the low pressure fuel hose quick-connector (A)
is completely connected to the high pressure fuel pump by the
locking sound.
|
| • |
Double-check the complete connection of the low pressure fuel
hose to the high pressure fuel pump by pulling it after connecting.
|
| • |
Be sure to install the high pressure fuel pipe (B) to the specified
torques.
|
| • |
Because fuel leak may cause fire, thoroughly inspect leakage
of all fuel line connection parts at engine start condition.
|
|
| • |
Before installing the high pressure fuel pump, position the
roller tappet in the lowest position by rotating the crankshaft.
Otherwise the installation bolts may be broken because of tension
of the pump spring.
|
| • |
Do not reuse high pressure fuel pipe.
|
| • |
When tightening the installation bolts of the high pressure
fuel pump, pretighten them by hand first, and then tighten them
in turns to the specified torque in small steps (0.5 turns).
|
| • |
Install the component to the specified torque.
|
| • |
First, secure the fasteners in place by pretightening them by
hand. Then, tighten them to the specified torque using a torque
wrench.
Bolts or nuts not tightened in a straight line with the matching
bolt holes or fittings may cause fuel leakage due to broken
threads.
|
| • |
Note that internal damage may occur when the component is dropped.
In this case, use it after inspecting.
|
|
| • |
Apply engine oil to the O-ring (A) of the high pressure fuel
pump, the roller tappet (B), and the protrusion (C). Also apply
engine oil to the groove on the location where the protrusion
(C) is installed.
|
|
| • |
Use the special service tool [SST No. : OK353-F6100] to install
the high pressure fuel pump.
|
|
| 1. |
Install in the reverse order of removal.
