Step-by-Step Instructions
1. Locate the Fuel Filter
The diesel fuel filter is typically located under the hood, near the engine. Refer to your vehicle’s owner’s manual for the exact location.
2. Disconnect the Battery
For safety, disconnect the negative terminal of the battery before working on the fuel system.
3. Drain the Fuel
Place a drain pan under the fuel filter. Using a wrench, loosen the drain plug at the bottom of the filter and allow the fuel to drain into the pan.
4. Remove the Fuel Lines
Use a wrench to loosen the fuel line clamps and disconnect the fuel lines from the filter. Be careful not to spill any fuel.
5. Remove the Old Filter
Using a wrench, loosen the filter mount and carefully remove the old fuel filter.
6. Prime the New Filter
Fill the new fuel filter with diesel fuel and insert the priming plug. Using a pump or by hand, prime the filter by repeatedly squeezing it until fuel flows out of the priming plug.
7. Install the New Filter
Align the new fuel filter with the filter mount and tighten it securely using a wrench.
8. Reconnect the Fuel Lines
Attach the fuel lines to the new filter and tighten the clamps securely.
9. Bleed the Air from the Fuel System
Turn the ignition key to the “On” position but do not start the engine. This will activate the fuel pump and purge any air from the fuel system.
10. Start the Engine
Once the fuel system is bled, start the engine and check for any leaks.
Additional Tips
- Replace the fuel filter regularly as per the manufacturer’s recommended intervals.
- Use only genuine Toyota fuel filters for optimal performance.
