Hyundai Venue: Fuel Delivery System / Fuel pressure test
| 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 diagnostic
tool 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).

| (2) |
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
|
|
• |
If the gauge reading should not be held, repair
or replace the related part (Refer to the table
below).

Other information:
Turn the knob to the right to increase the fan speed and airflow. Turn the knob
to the left to decrease fan speed and airflow.
Setting the fan speed control knob to the “0” position turns off the fan.
NOTICE
Operating the fan speed when the ignition switch is in the ON position could
cause the battery to discharge...
Replacement
1.
Remove the front seat assembly.
(Refer to Front Seat - "Front Seat Assembly")
2.
Separate the front seat belt buckle wiring (A).
3.
Loosen the mounting bolt and remove the front seat belt buckle (B)...
Categories
This gauge indicates the approximate amount of fuel remaining in the fuel tank.
Information
The fuel tank capacity is given in chapter 2.
The fuel gauge is supplemented by a low fuel warning light, which will
illuminate when the fuel tank is nearly empty.
On inclines or curves, the fuel gauge pointer may fluctuate or the low
fuel warning light may come on earlier than usual due to the movement of fuel
in the tank.
