Gather Your Tools and Supplies
Before you begin, ensure you have the following tools and supplies:
- New fuel line: Choose a fuel line specifically designed for lawn mowers, ensuring it’s the correct length and diameter for your model.
- Fuel line clamps: These clamps secure the fuel line to the carburetor and fuel tank.
- Wrench set: You’ll need wrenches to loosen and tighten the clamps holding the fuel line in place.
- Screwdriver: You might need a screwdriver to access the fuel line in some models.
- Safety glasses: Always wear safety glasses to protect your eyes from fuel spills or flying debris.
- Gloves: Wear gloves to protect your hands from fuel and grime.
- Rag or shop towel: Use this to clean up spills and catch drips.

- Fuel tank siphon: This tool can help safely remove fuel from the tank before working on the fuel line.
- Fuel stabilizer: To prevent fuel from deteriorating in the tank during storage.
Safety Precautions: The First Priority
Working with gasoline can be dangerous. Therefore, prioritize safety throughout the repair process:
- Work in a well-ventilated area: Gasoline fumes can be harmful, so ensure good airflow during the process.
- No smoking: Avoid smoking or using open flames near gasoline.
- Keep gasoline away from heat sources: Store gasoline in a cool, well-ventilated area, away from direct sunlight or heat.
- Wear proper safety gear: Always wear safety glasses, gloves, and close-toed shoes.

Step-by-Step Guide to Replacing Your Lawn Mower Fuel Line
Now, let’s get down to business and tackle the fuel line replacement:
1. Prepare the Lawn Mower:
- Turn off the engine and let it cool down: Ensure the engine is completely off and has cooled down before working on it.
- Remove the spark plug wire: Disconnect the spark plug wire from the spark plug to prevent accidental starting.
- Drain the fuel tank: Using a fuel tank siphon, carefully remove the fuel from the tank. Alternatively, you can use a small container to catch the fuel, but be cautious not to spill it.
2. Locate and Disconnect the Old Fuel Line:
- Identify the fuel line: The fuel line runs from the fuel tank to the carburetor. It’s usually a black or clear rubber hose.
- Locate the fuel line clamps: You’ll find clamps at the points where the fuel line connects to the tank and carburetor.
- Loosen the clamps: Use your wrench set to carefully loosen the clamps securing the fuel line. Be gentle to avoid damaging the fuel line or surrounding components.
- Disconnect the fuel line: Once the clamps are loosened, gently pull the fuel line free from its connections.
3. Install the New Fuel Line:
- Cut the new fuel line to size: Using the fuel line cutter, precisely cut the new fuel line to the correct length. Make sure it’s long enough to reach comfortably between the tank and carburetor, with a slight slack.
- Slide the new fuel line onto the tank connection: Carefully slide the new fuel line onto the fuel tank outlet.
- Secure the fuel line to the tank: Tighten the fuel line clamp on the tank connection firmly, ensuring a secure fit.
- Connect the new fuel line to the carburetor: Slide the other end of the fuel line onto the carburetor inlet.
- Secure the fuel line to the carburetor: Tighten the fuel line clamp on the carburetor connection, making sure it’s secure.
4. Check for Leaks:
- Inspect for leaks: Carefully examine the fuel line connections for any leaks. If you see any fuel dripping, tighten the clamps further.
- Wipe away any spills: Use a rag or shop towel to clean up any fuel spills.
5. Reassemble the Lawn Mower:
- Reconnect the spark plug wire: Carefully reconnect the spark plug wire to the spark plug.
- Refill the fuel tank: Once you’ve confirmed there are no leaks, carefully refill the fuel tank with fresh gasoline and add a fuel stabilizer to help prevent fuel deterioration.
Troubleshooting Tips for Fuel Line Issues:
If you’re still having trouble with your lawn mower after replacing the fuel line, here are some troubleshooting tips:
- Check the fuel filter: A clogged fuel filter can restrict fuel flow, even with a new fuel line.
- Inspect the carburetor: A dirty or damaged carburetor can also cause fuel flow issues.
- Verify the fuel line orientation: Ensure the fuel line is routed correctly and not kinked or pinched.
- Check for air leaks: Air leaks in the fuel line or carburetor can prevent fuel from reaching the engine.
