Tools Needed
Before starting, gather the necessary tools. You will need a fuel siphon pump, a gas can, and a clean cloth. Having these tools will make the job easier and safer.
Step-by-step Process
First, ensure the lawn mower is on a flat surface. This makes it stable. Then, disconnect the spark plug wire. This step is crucial for safety. Next, open the fuel cap.

Removing Residue
First, drain the fuel tank completely. Use a siphon pump for this task. Next, inspect the tank for any debris or sludge. You will need a clean cloth and a long brush. Wipe away any visible residue. For stubborn grime, use a little bit of clean gas on the cloth. This helps to loosen the debris. Make sure to wear gloves for protection.
Drying The Tank
After removing the residue, it’s time to dry the tank. Use a dry, clean cloth to wipe down the inside. Ensure there is no moisture left. You can also let the tank air dry. This prevents any water from mixing with the new fuel. A dry tank ensures the engine runs without issues. Now, your fuel tank is ready for fresh gas.
Replacing The Fuel Filter

Do not overfill. Replace the gas cap securely. Dispose of any old gas properly. Check the owner’s manual for specific guidelines.
