Gas Leaf Blower: What should I do if my leaf blower leaks gas?

Move the leaf blower to a well-ventilated area and check the fuel lines for cracks if your leaf blower leaks gas. Replace the fuel lines if they're cracked and leaking fuel.

If fuel leaks from the carburetor, rebuild or replace the carburetor to prevent gas from leaking. Replace the fuel tank cap if its seal is damaged and leaking. Check the fuel tank and replace if it's damaged.

Replace a fuel line that's brittle or damaged. Be careful to install new fuel lines on the engine the same way the original fuel lines were configured.
