Hyundai Venue: Fuel Delivery System / Fuel pressure test

Hyundai Venue (QX) (2020-2022) Service Manual / Engine Control / Fuel System / Fuel Delivery System / Fuel pressure test

Fuel Pressure Test
1.
Release the residual pressure in fuel line.
(Refer to Fuel Delivery System - "Release Residual Pressure in Fuel Line")
Hyundai Venue. Fuel pressure test   
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).

    Fuel gauge

    Hyundai Venue. Fuel gauge

    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.
