Disconnect the spark plug
Disconnecting the spark plug is the first step in performing any service on your lawnmower. It is important to do this before removing the fuel line to ensure safety and avoid accidents. Here is a step-by-step guide on how to disconnect the spark plug:
- Locate the spark plug: The spark plug is usually located near the engine or under the hood of the lawnmower. It is often positioned close to the fuel tank or the carburetor.
- Remove the spark plug wire: Carefully detach the spark plug wire from the spark plug. Make sure to do this gently to avoid any damage.
- Secure the wire: Once the wire is removed, secure it away from the spark plug. This step is crucial to prevent accidental contact between the wire and the plug during the service.
- Verify the disconnection: Before proceeding with any other maintenance or repair work, ensure that the spark plug is indeed disconnected. This step ensures that the lawnmower engine is completely shut off and will not start unexpectedly.
- Perform necessary service: After disconnecting the spark plug, you can proceed with removing the fuel line or performing other maintenance tasks on your lawnmower. Remember to exercise caution when working with fuel systems.
- Reconnect the spark plug: Once you have completed your service or repair work, remember to reconnect the spark plug wire securely. This will ensure that your lawnmower can operate normally again.
Remember to always refer to your lawnmower's owner's manual for specific instructions and safety precautions. Working with fuel systems requires caution, so it is important to be thorough and careful throughout the process.

Locate the fuel line
Before you start, it is important to locate the fuel line and familiarise yourself with the underside of your lawnmower. The fuel line is usually a clear, plastic hose that runs from the gas tank to the carburetor. It is often located near the engine or under the hood.
First, locate the gas tank on your lawnmower. It is usually found near the engine or under the hood. Once you have located the gas tank, check to see if there is a fuel shut-off valve. If there is, turn it to the "off" position. This will prevent any further fuel from flowing through the fuel line.
Next, you need to identify the fuel line. It is typically a clear, plastic hose that connects the gas tank to the carburetor. It may have a fuel filter attached, which is either located at the base of the tank or outside, midway along the fuel line. The fuel filter can be recognised as a convex attachment to the hose.
If you are unsure whether your lawnmower has a fuel line, refer to the owner's manual. Most manuals can be easily found online. It is important to familiarise yourself with the moving sections of your unit before attempting any maintenance or repairs.

Drain the gas
Draining the gas tank of your lawnmower is a crucial aspect of routine maintenance, ensuring the engine's longevity and reliability. Old gasoline can cause starting issues, engine damage, and other fuel system issues. It is recommended to drain the gas from your lawnmower at the end of each mowing season.
- Set up your lawnmower on a flat, even surface.
- Disconnect the spark plug wire to avoid accidents and secure it away from the plug.
- Locate the gas tank on your lawnmower. It is usually located near the engine or under the hood.
- If there is a fuel shut-off valve, turn it to the "off" position.
- Open the mower's fuel tank by removing the cap.
- If you are using a siphon pump:
- Insert the intake or longer siphon pump hose into the gas tank, making sure it is submerged in the gasoline but not touching the bottom of the tank to avoid collecting sediment.
- Place the shorter hose of the siphon pump into an empty gasoline can to collect the old gas. Hold the gas can lower than the gas tank to utilise gravity for a better flow.
- Begin pumping the siphon to start the gas flow through the hose.
If you are not using a siphon pump:
- Carefully disconnect the fuel line from the carburetor.
- Place a draining pan or container below the disconnected fuel line.
- Allow the gas to drain from the fuel line into the container.
- Reconnect the fuel line once the gas tank is empty.
- Reconnect the spark plug wire and run the mower to burn off any remaining gas.
Note: Always exercise caution when working with fuel systems. Familiarise yourself with the owner's manual and the moving sections of your lawnmower before beginning any maintenance.

Check for blockages
Before you begin any maintenance on your lawnmower, make sure the machine is unplugged or turned off. Remove the spark plug lead and secure it away from the plug.
Now, you can start checking for blockages. Firstly, check the fuel line for any blockages or clogs. Use a flashlight to inspect the line for any debris, hairline cracks, holes, or cracks. If the fuel line appears compromised, it is best to replace it.
Next, check the fuel filter for any blockages. The fuel filter may be located at the base of the tank, where the fuel enters the fuel line, or it may be located outside the tank, midway along the fuel line. If you have a fuel filter, it is recommended to replace it, as it is difficult to visually check for blockages.
Additionally, look inside your gas tank. Many tanks have a screen over the fuel outlet to the gas line; ensure this screen is not blocked. If it is blocked, remove and replace it with one from the lawn mower manufacturer. Also, check for any debris or damage inside the tank.
Finally, ensure there is no blockage in the gas cap. Lawn mower gas caps are designed to allow air into the tank to prevent vapor lock, which stops gasoline from flowing from the tank to the fuel line. Check if there is any plastic or sealant blocking the cap, and if so, remove it and try to start the engine.

Replace the fuel line
Before you begin any maintenance on your lawnmower, make sure the machine is unplugged or otherwise turned off. Remove the spark plug lead and secure it away from the plug.
Now, you can start to replace the fuel line. First, locate the gas tank on your lawnmower. It's usually located near the engine or under the hood. If there's a fuel shut-off valve, turn it to the "off" position. If your lawnmower doesn't have a fuel valve, clamp the fuel line to keep the gas from flowing.
Next, open the mower fuel tank by removing the cap. If your mower uses ethanol-free fuel, it's advisable to drain the tank or use a fuel stabilizer for long-term storage. To drain the tank, you can use a siphoning technique or disconnect the fuel line from the carburetor.
If you choose to siphon the gas, insert the intake or longer siphon pump hose into the gas tank, ensuring it's submerged in the gasoline but not touching the bottom of the tank to avoid collecting sediment. Put the shorter hose of the siphon pump into an empty gasoline can to collect the old gas. Hold the gas can lower than the gas tank to allow gravity to help with the flow and begin pumping.
If you choose to disconnect the fuel line, carefully detach it from the carburetor. Place a draining container or pan below the disconnected fuel line and allow the gas to drain.
Once the tank is empty, you can replace the fuel line. Refer to the owner's manual for your lawnmower to determine the correct parts to use. Only use parts recommended by the manufacturer. Reattach the fuel tank or install a new one, fastening it firmly with the cap screws.
Finally, connect the gas lines and filters to the tank, but not to the carburetor. Place your hand over the tank opening to create a seal and blow through your hand to ensure that air can pass unobstructed through the fuel lines. Then, connect the gas line to the carburetor and fill the tank.

Frequently asked questions
Before you begin any maintenance, make sure the machine is unplugged or otherwise turned off. Disconnect the spark plug wire and remove the gas cap. Locate the fuel line connecting the gas tank to the carburetor. Carefully disconnect the fuel line from the carburetor. Place a draining container or pan below the disconnected fuel line. Allow the gas to drain from the fuel line into the container.
Draining gas from a lawn mower engine is a simple chore that can save you from carburetor problems later on. Old gasoline can clog the carburetor, degrade over time, and lead to engine damage.
Once you have replaced the lines, filter, and ensured that there is no blockage in the tank itself, connect the gas lines and filters to the tank, but not to the carburetor. Place your hand over the tank opening, creating a seal. Blow through your hand to ensure that air can pass unobstructed through your fuel lines.
Always read the engine and equipment manual(s) before starting. Fuel and its vapors are extremely flammable and explosive. Put on eye protection as gas may sometimes spray out and get in your eyes.
