Why is Changing Your Fuel Filter Important?
The fuel filter serves as a barrier, trapping impurities and contaminants in the fuel before it reaches the engine. Over time, the filter can become clogged, restricting fuel flow and potentially damaging the fuel pump and injectors. Regular fuel filter replacement is essential to:
- Maintain engine performance and prevent engine damage
- Improve fuel efficiency by ensuring a steady supply of clean fuel
- Extend the lifespan of your Hilux

- Wear gloves to protect your hands from fuel and dirt.
2. Locate the Fuel Filter
- The fuel filter is typically located on the passenger side of the engine, near the fuel tank.
- Follow the fuel lines to identify the filter housing.
3. Disconnect the Fuel Lines
- Use a fuel filter wrench to loosen the fuel line fittings on both sides of the filter.
- Be cautious as fuel may leak out.
- Place a rag or shop towel under the fittings to catch any spilled fuel.
4. Remove the Old Filter
- Once the fuel lines are disconnected, carefully unscrew the filter housing.
- Remove the old fuel filter and inspect it for signs of contamination or damage.
5. Install the New Filter
