Materials You’ll Need

• New fuel filter
• 14mm wrench
• Rags or paper towels
• Safety glasses

Safety First

Before you begin, it’s important to take a few safety precautions:

• Park your car on a level surface and engage the parking brake.
• Allow the engine to cool completely to avoid burns.
• Wear safety glasses to protect your eyes from any fuel spray.

Locate the Fuel Filter

The fuel filter is usually located under the car, near the fuel tank. In the Toyota Yaris, it’s typically found on the driver’s side, just behind the front wheel.

Step-by-Step Instructions

1. Disconnect the Negative Battery Terminal

Before touching the fuel filter, it’s crucial to disconnect the negative battery terminal. This will prevent any electrical sparks that could ignite fuel vapors.

2. Locate the Fuel Line Connections

The fuel filter will have two fuel line connections, one on each end. Use the 14mm wrench to loosen the bolts that secure these connections.

3. Release Fuel Pressure

Before disconnecting the fuel lines, you need to release the fuel pressure in the system. To do this, start the engine and let it run for a few seconds until it stalls. Then, turn the ignition key to the “OFF” position.

4. Disconnect the Fuel Lines

Once the fuel pressure has been released, you can disconnect the fuel lines from the filter. Use a rag or paper towels to catch any spilled fuel.

5. Remove the Fuel Filter

The fuel filter is usually held in place by a bracket or clamp. Use the 14mm wrench to loosen the bolts or screws that secure the bracket or clamp. Then, remove the fuel filter.

6. Install the New Fuel Filter

Take the new fuel filter and insert it into the bracket or clamp. Make sure the arrows on the filter point in the direction of the fuel flow. Tighten the bolts or screws to secure the filter.

7. Reconnect the Fuel Lines

Reconnect the fuel lines to the new filter. Make sure the connections are tight to prevent fuel leaks.

8. Reconnect the Negative Battery Terminal

Reconnect the negative battery terminal.

9. Start the Engine and Check for Leaks

Start the engine and let it run for a few minutes. Check for any fuel leaks around the filter and fuel lines. If you notice any leaks, tighten the connections further.

Tips

• Use a new fuel filter every time you change it.
• If you’re not comfortable working on your car, it’s best to have the fuel filter changed by a mechanic.
• Keep a fire extinguisher nearby when working on your car’s fuel system.
