how to remove vz fuel filter

If you're looking to remove the fuel filter from your Holden Commodore VN VR VS VX VT VY VZ ASTRA BARINA, there are a few methods you can try. The fuel filter is typically located on the front side of the fuel tank, tucked behind the rear axle. You can use a fuel filter removal tool, which can be purchased online, or try a few DIY methods. Some people have used multi-grips to remove their fuel filters, but the connections may deteriorate over time. It's important to note that the Quick Connectors on the fuel lines are delicate and can be easily broken, so be cautious when attempting any fuel filter removal method.

Location of the fuel filter

The fuel filter is located on the front side of the fuel tank, on the right-hand side of the vehicle, tucked up near the floor pan behind the rear axle. It is held in place by a black plastic retaining clip, which is there to stop the plastic fuel lines from flapping around. The fuel lines will eventually fracture if the clip is not re-installed.

The fuel filter can be found up behind the driver's side rear wheel area. It is clipped on and off.

Some VZ Utes/Maloo's don't have an external fuel filter. On these vehicles, the fuel filter is part of the fuel pump assembly, which is inside the fuel tank.

In V8 Crewman models, the fuel filter is not external and is instead located inside the tank.

Removing the fuel pump fuse

To remove the fuel pump fuse from a VZ Commodore, follow these steps:

Firstly, locate the fuel filter. It is usually found on the front side of the fuel tank, on the right-hand side of the vehicle, tucked up near the floor pan behind the rear axle. It should be secured by a black plastic retaining clip.

Next, open the bonnet and locate the fuel pump fuse, which should be under the bonnet on the right-hand side. Remove this fuse, then start the engine and allow it to stall.

Now, you can proceed to squeeze the tangs on the side of the connector and then pull to remove the fuel filter. Take note of the flow direction when installing a new filter.

When installing a new filter, ensure you push the connectors onto the new filter in the correct direction, replace the fuse, and turn on the ignition. Allow the fuel system to prime, then start the engine and check for any leaks.

It is important to note that the Quick Connectors on the fuel lines are delicate and can be easily broken. There are tools available specifically for removing these connectors, which can make the process easier and reduce the risk of breakage.

Using a removal tool

To remove a VZ fuel filter using a removal tool, follow these steps:

First, open the engine bay and remove the fuel pump relay. Then, turn the ignition on and crank the engine—it will stall in a few seconds. This step is necessary to depressurise the fuel system and prevent fuel spray. Once the engine has stalled, turn the ignition off and remove the key.

Now, get under the vehicle and insert the removal tool on the outlet side (flat side) of the fuel filter. You may have to rotate the tool through 90 degrees as you insert it to unlock the four tangs inside the quick connector. Gently push the quick connector towards the removal tool (you may feel a gentle click), then pull the connector away from the tool and off the fuel filter tube. Some fuel will dribble out, so be careful not to make a mess or get fuel in your eyes.

Wrap a clean rag around the filter/loose connector and repeat the above steps on the other side of the fuel filter.

Note that there are specific tools available to help with this process, such as the T&E Tools 4412 ASTRA BARINA, which is designed for the Holden Commodore VZ model. These tools can make removing the fuel filter a much easier process.

Depressurising the fuel system

Firstly, locate the fuel pump fuse, which is usually under the bonnet on the right-hand side (RHS) of the engine bay. Remove this fuse to disable the fuel pump. Then, turn the ignition on and crank the engine. The engine will stall after a few seconds due to the disabled fuel pump. Once the engine has stalled, turn the ignition off and remove the key.

At this point, the fuel system should be depressurised. To confirm this, carefully check for any signs of pressure or leaks in the system. If there are no signs of pressure, it is safe to proceed with the next steps of removing the fuel filter. It is important to exercise caution when working with the fuel system to avoid any spills or leaks.

The next step is to get under the vehicle and locate the fuel filter. It is usually located on the front side of the fuel tank, tucked up near the floor pan behind the rear axle. Once you have located the fuel filter, you can proceed with the removal process.

To remove the fuel filter, you may need a special removal tool that is designed for the quick-connect fittings. This tool can be purchased from automotive stores, such as Autopro or Repco. Insert the removal tool on the outlet side (flat side) of the fuel filter and gently push it into the connector. You may need to rotate the tool through 90 degrees to unlock the tangs inside the quick connector. These tangs are delicate, so be careful not to apply too much force.

By following these steps, you can safely depressurise the fuel system and remove the fuel filter from a VZ Commodore. Remember to refer to specific maintenance guidelines for your vehicle and always take the necessary safety precautions when working with automotive systems.

Get under the vehicle and insert the removal tool on the outlet side of the fuel filter, gently wrapping it around the old fuel filter outlet tube. Push the tool into the connector, possibly rotating it 90 degrees, and unlock the four tangs inside the quick connector. Then, push the connector towards the filter, push the clips in, and pull it off.
