Hyundai Creta: Fuel Delivery System / Repair procedures
| 1. |
Release the residual pressure in fuel line.
(Refer to Fuel Delivery System - "Release Residual Pressure in Fuel
Line")
| •
|
When removing the fuel pump fuse, a Diagnostic Trouble
Code (DTC) may occur. Delete the code with the GDS after
completion of "Release Residual Pressure in Fuel Line"
work.
|
|
|
| 2. |
Install the Special Service Tool (SST).
| (1) |
Disconnect the fuel feed tube from the delivery pipe.
|
• |
There may be some residual pressure even after
“Release Residual Pressure in Fuel Line” work,
so cover the hose connection with a shop towel
to prevent residual fuel from spilling out before
disconnecting any fuel connection.
|
|
|
| (2) |
Install the special service tool for measuring the fuel pressure
in between the fuel feed tube and the fuel delivery pipe (Refer
to the figure below).
|
|
| 3. |
Inspect fuel leakage on connections among the fuel feed tube, the delivery
pipe, and the SST components with IG ON.
|
| 4. |
Measure Fuel Pressure.
| (1) |
Start the engine and measure the fuel pressure at idle.
|
Fuel Pressure :
323 ~ 363 kPa (3.3 ~ 3.7 kgf/cm², 46.8 ~ 52.6 psi)
|
|
• |
If the fuel pressure differs from the standard
value, repair or replace the related part (Refer
to the table below).

Stop the engine, and then check for the change in the fuel pressure
gauge reading.
|
Standard Value : The gauge reading should hold for about
5 minutes after the engine stops
|
|
