Replacing the axial fuel in a Toyota Matrix can be a challenging task. Depending on the location of the filter, it may be possible to replace it at home, but it will likely require lifting and supporting the vehicle to access the filter, and possibly removing under-body panelling. The process may also involve draining coolant and oil, removing engine components, and replacing the intake manifold gasket. It is important to use high-quality, OEM parts when replacing fuel injectors to ensure even power across the engine and a proper air-fuel mixture.

What You'll Learn
Lifting and supporting the vehicle
First, the vehicle must be lifted safely to access the filter. This may require the use of a jack or a lift to raise the car to a comfortable working height. It is crucial to ensure that the vehicle is stable and secure before proceeding. Once the vehicle is lifted, it should be supported by jack stands or other sturdy supports to prevent it from falling or shifting during the repair.
Depending on the location of the filter, under-body paneling may need to be removed to access it. This step may require additional tools and careful manoeuvring to avoid damaging other components. It is important to consult a repair manual or seek advice from a professional if you are unsure about the specific steps required for your vehicle.
Fuel filters are more easily replaced with a set of fuel line release tools, which can be purchased from auto parts stores or online. These tools allow for the safe removal of fuel lines without breaking any fragile plastic clips. Before disconnecting the fuel lines, it is essential to catch any fuel that may fall from the filter or line during this process to prevent spills or leaks.
Additionally, it is important to note that the fuel pump may be located inside or outside the fuel tank. If it is inside, the tank will need to be drained before removing the access panel. Once the pump is outside the tank, the fuel lines can be disconnected, and the pump can be removed and replaced. A final check should be performed to ensure there are no fuel leaks and that the problem has been resolved.

Draining fuel
When draining fuel, it's important to be careful to catch any fuel that falls from the filter or line. You may also need to drain the coolant and oil, and remove many engine components to access the fuel injector. Some cars, however, are designed with plastic intake manifolds that do not have oil or coolant passages, making this process easier.
Once you have access, the fuel injector is disconnected from the fuel rail and electrical connector and removed. A new one can then be installed in its place. When replacing fuel injectors, it's important to use high-quality, OEM parts to ensure even power across the engine and a proper air-fuel mixture for all cylinders.
In some cases, you may also need to drain fuel before removing the access panel to replace the fuel pump. The pump can be either inside or outside the fuel tank, and fuel is sucked out of the tank and pushed through a line to a filter, and then to the fuel injectors.

Disconnecting fuel lines
Disconnecting the fuel lines of a Toyota Matrix can be a complex process. It is important to note that fuel filters are more easily replaced with a set of fuel line release tools, which can be purchased from auto parts stores or online. These tools allow the user to remove the fuel lines without breaking any of the fragile plastic clips.
Before disconnecting the fuel lines, it is crucial to lift and safely support the vehicle to access the filter. In some cases, under-body panelling may need to be removed. It is also important to catch any fuel that falls from the filter or line during this process.
The fuel pump, which delivers gas from the fuel tank to the fuel injectors, can be located either inside or outside the fuel tank. When the pump is outside the tank, a mechanic will disconnect the fuel lines, remove the pump, and install a new one. Draining the fuel before removing the access panel may be necessary in some cases.
Additionally, the fuel injector, which is connected to the fuel rail and electrical connector, may need to be disconnected and replaced. This can be a large job, potentially involving the draining of coolant and oil, the removal of engine components, and the replacement of the intake manifold gasket. However, some cars have plastic intake manifolds without oil or coolant passages, making this process easier.

Removing the old pump
First, park your car on a level surface and set the parking brake. Then, locate the pump assembly in the fuel tank. If the pump is inside the fuel tank, you will need to remove the access cover. If the pump is outside the tank, you will need to drain the fuel before removing the access panel.
Next, support the fuel tank using a jack stand and a block of wood. Remove the entire pump assembly, including the pump and the fuel level sending unit, and lower the tank. Remove every hose clamp, disconnect the fuel line or fuel tank hose, and extract the original pump from the gas tank.
Once the old pump is removed, you can install the new one.

Installing the new pump
To install the new pump, you will need to drain the fuel from the tank. This can be done by removing the access panel and disconnecting the fuel lines. Once the pump is outside the tank, the old pump can be removed and the new one installed.
When replacing the pump, it is important to use high-quality, OEM parts to ensure even power across the engine and a proper air-fuel mixture for all cylinders. The new pump should be connected to the fuel rail and electrical connector.
After the new pump is installed, the fuel lines will need to be reconnected and the access panel replaced. It is important to check for any fuel leaks and ensure that the problem has been solved.
If you are replacing the fuel door, you will need to drill out the old rivet and install a new waterproof rivet. This can be done with a pop-rivet gun. It is important to note that some inner panels may need to be removed to access the back of the rivet.
