How to Replace a Log Splitter Fuel Line

 

file

This DIY repair guide explains how to replace the fuel line on a log splitter. The fuel line carries gas from the fuel tank to the carburetor. A clogged, bent or cracked fuel line keeps the gas from flowing the engine, so the log splitter won’t start. Check the fuel lines and clear any clogs. Replace cracked or bent fuel lines using the manufacturer-approved replacement part.
