Gas Leaf Blower: Leaking 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 the leaf blower fuel lines
A leaf blower's fuel lines carry fuel from the tank to the carburetor and from the primer bulb to the fuel system. Fuel lines become brittle over time and can crack or break. 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.
Replace the leaf blower carburetor
The leaf blower's carburetor mixes air and gasoline in the proper proportions to create a combustible gas. If the engine starts and then sputters, or doesn't start at all due to lack of fuel, you might need to replace carburetor. It's often more cost effective and practical to replace the carburetor rather than rebuild it.
