Chainsaw Fuel Cap Assembly 580940901

This part is the replacement fuel cap assembly for your chainsaw. It is made of black plastic and is sold individually. The fuel cap prevents fuel from spilling out of the chainsaw and prevents debris from entering the fuel tank. If the fuel cap is stripped or missing the O-ring, it can cause a leak, and will need to be replaced. To replace the fuel cap simply screw the old one out and screw the new one in, ensuring you have a tight seal. This is an authentic OEM part sourced directly from the manufacturer.
