Materials You’ll Need

- Fresh fuel
Step-by-Step Instructions
1. Locate the Fuel Filter
The location of the fuel filter varies depending on the make and model of your vehicle. It’s typically found either under the hood near the engine or underneath the vehicle along the fuel line. Consult your vehicle’s owner’s manual for the exact location.
2. Apply Fuel Filter Cleaner
Once you’ve located the fuel filter, apply a generous amount of fuel filter cleaner or carburetor cleaner to the filter’s inlet and outlet ports. Use the spray bottle to ensure even distribution. Allow the cleaner to soak for 15-20 minutes.
3. Flush the Filter
Using the funnel, pour fresh fuel through the fuel filter‘s inlet port. The fuel will flush out the dissolved contaminants and debris. Continue flushing until the fuel runs clear.
4. Repeat Steps 2 and 3
If the fuel filter is still clogged, repeat steps 2 and 3. Allow the cleaner to soak for a longer duration and flush with more fresh fuel.
5. Dry the Filter
After flushing the filter, use rags or paper towels to wipe away any excess fuel and cleaner. Ensure the filter is completely dry before reconnecting it.
6. Reconnect the Filter
Reinstall the fuel filter to its original location. Tighten the connections securely but avoid overtightening.
7. Start the Engine
Start your vehicle and allow it to run for a few minutes. The engine may hesitate or stall initially as the fuel system fills up again. Keep the engine running until it runs smoothly.
