Changing The Fuel Filter In Your Azera: Step-By-Step Guide

The fuel filter on a Hyundai Azera is located inside the fuel tank. To replace it, you will need to remove the service cover in the trunk, disconnect the fuel pump connector, and wait for the engine to stall. You will then need to disconnect various tubes and connectors, remove the mounting bolts, and lift out the fuel pump assembly. The fuel filter is inside the pump assembly, so you will need to carefully disassemble it and transfer the necessary parts to a new filter assembly. Finally, you can install the new assembly by following the removal steps in reverse.

Disconnect the fuel pump connector

To disconnect the fuel pump connector, you must first locate the service cover in the trunk of your Azera. Once you have found it, open it and look for the fuel pump connector, which should be labelled or otherwise indicated. When you have identified the fuel pump connector, simply disconnect it.

It is important to exercise caution when performing this task, as there may still be pressure in the fuel feed quick connector. Before proceeding, ensure that you have allowed the engine to stall by following the previous steps outlined in the service manual.

After disconnecting the fuel pump connector, you will need to disconnect the suction tube quick connector, fuel feed quick connector, fuel tank pressure sensor connector, and fuel pump and sub fuel sender connector. These components should be clearly labelled and can be safely disconnected once the fuel pump connector has been detached.

It is recommended to place a piece of cardboard underneath your vehicle when performing this task to avoid staining your driveway or garage floor with any spilled fuel. Safety goggles and gloves are also advised to protect your eyes and skin from potential fuel exposure.

Start the engine and wait for the fuel to be exhausted

To replace the fuel filter on a Hyundai Azera, you will need to start by removing the service cover in the trunk and disconnecting the fuel pump connector. Next, start the engine and wait until the fuel in the fuel line is exhausted. This will cause the engine to stall and shut off.

This step is crucial for safety reasons, as it ensures that there is no residual fuel pressure in the lines that could cause leakage or spray when you begin to disconnect the fuel lines and remove the fuel pump assembly. It is important to exercise caution when working with flammable liquids like gasoline, as they pose a fire hazard. Always refer to your service manual for detailed instructions on how to perform this procedure correctly and safely.

Once the engine has stalled, turn the ignition switch off. Now you can proceed to disconnect the suction tube quick-connector, fuel feed quick-connector, fuel tank pressure sensor connector, and fuel pump and sub-fuel sender connector. With these disconnected, you can then unfasten the fuel pump mounting bolts and remove the fuel pump assembly, giving you access to the fuel filter.

The fuel filter is located within the fuel pump assembly, which is why you need to remove it to access and replace the filter. Replacing the fuel filter itself may require special tools or procedures, so it is recommended to refer to the service manual or seek advice from a qualified technician if you are unsure about any part of the process.

Disconnect the suction tube quick-connector, fuel feed quick-connector, fuel tank pressure sensor connector, and fuel pump and sub fuel sender connector

Disconnecting the suction tube quick-connector, fuel feed quick-connector, fuel tank pressure sensor connector, and fuel pump and sub fuel sender connector is a crucial step in changing the fuel filter on your Azera. Here's a detailed guide on how to perform this step safely and effectively:

Preparation:

• Remove the service cover in the trunk. It is usually located on the passenger side.
• Disconnect the fuel pump connector.
• Start the engine and wait until the fuel in the fuel line is exhausted.
• Once the engine stalls, turn the ignition switch off.

Disconnecting the Connectors:

• Suction Tube Quick-Connector: Locate the suction tube quick-connector (usually labelled as "A"). Carefully lift the retainer and slide off the tube. Have some rags ready to absorb any pressurised fuel that may be released.
• Fuel Feed Quick-Connector: This is typically labelled as "B". Again, lift the retainer and slide off the tube, being cautious of any released fuel.
• Fuel Tank Pressure Sensor Connector: This is typically labelled as "C". Disconnect this connector carefully.
• Fuel Pump & Sub Fuel Sender Connector: Labelled as "D", disconnect this connector as well.

Once you have safely disconnected all the connectors, you can proceed to unfasten the fuel pump mounting bolts and remove the fuel pump assembly. It is important to work in a well-ventilated area or outdoors to allow fumes to dissipate. Always refer to your service manual for specific instructions and safety precautions for your Azera model.

Unfasten the fuel pump mounting bolts and remove the fuel pump assembly

To unfasten the fuel pump mounting bolts and remove the fuel pump assembly, you will need to follow the steps below:

Preparation:

• Remove the service cover in the trunk.
• Disconnect the fuel pump connector.
• Start the engine and wait until the fuel in the fuel line is exhausted.
• After the engine stalls, turn the ignition switch off.

Disconnect:

Disconnect the suction tube quick-connector, fuel feed quick-connector, fuel tank pressure sensor connector, and fuel pump and sub-fuel sender connector.

Unfasten and Remove:

• Unfasten the fuel pump mounting bolts.
• Remove the fuel pump assembly.

Now that you have successfully removed the fuel pump assembly, you can install the new fuel pump assembly by following the reverse order of the removal procedure.

Reinstall the fuel pump assembly

To reinstall the fuel pump assembly, you will need to follow the steps outlined in the Hyundai service manual. Here is a detailed guide to help you through the process:

Step 1: Prepare the Vehicle

• Open the trunk and remove the service cover.
• Disconnect the fuel pump connector and wait for the engine to stall. Turn off the ignition switch.

Step 2: Disconnect Components

Disconnect the suction tube quick-connector, fuel feed quick-connector, fuel tank pressure sensor connector, and fuel pump & sub fuel sender connector.

Step 3: Remove the Fuel Pump Assembly

• Unfasten the fuel pump mounting bolts.
• Carefully lift and remove the fuel pump assembly from the fuel tank.

Step 4: Reinstall the Fuel Pump Assembly

• Install the new fuel pump assembly by following the reverse order of the removal procedure.
• Ensure that all connectors and components are securely fastened and reattached.
• Tighten the fuel pump mounting bolts to the specified torque (2.0 ~ 2.9 N·m or 0.2 ~ 0.3 kgf·m, 1.4 ~ 2.2 lbf·ft).

Step 5: Final Checks

• Verify that all connectors and components are properly connected and secured.
• Check for any fuel leaks around the fuel pump assembly and connectors.
• Reattach the service cover in the trunk.

By following these steps, you can confidently reinstall the fuel pump assembly on your Hyundai Azera, ensuring a secure and proper installation.
