Fuel line leak or?

I have a leak from my carburetor underneath by the lower fuel line. It kinda looks like there could be a hole way up between the 2 screw-in fuel lines. Could it be leaking from someplace other than the fuel lines? I have replaced both screw-in adapters, but it is still leaking, the gaskets are great. My dad passed and I am the new mechanic on the farm. I am defiantly a newbie. Please help me guys
