Gas Leaf Blower: Leaking gas

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.

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.

The leaf blower 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 can rebuild the carburetor. Rebuild kits are available for most carburetors and contain essential components for rebuilding a leaf blower carburetor, such as diaphragms, seals and gaskets. You can sometimes fix a fuel supply problem by dismantling and cleaning a carburetor. Use the kit to rebuild the carburetor after cleaning it.
