Have you ever struggled with removing a fuel line from a barbed fitting? A technician recommends using panel clip pliers to remove the stuck hoses. While this tool is more commonly used in the automotive industry to remove the “Christmas Tree” clips from a door panel, it can be used in the marine industry as well to help disconnect
stubborn fuel, vent, and cooling lines.

Yamaha District Manager Jesse Dayton also suggests trying radiator hose picks and/or hose pliers for disconnecting lines.

You should never pull on a line, hose, or clip to disconnect it. Make sure to use tools properly. Not using tools properly could cause damage to the hoses, resulting in leaks. Simply find the right tool that works, and it will make your job a lot easier.
