Sounds like good progress. Boil can be conducted heat but usually is heat radiated into the lines. Black fuel hoses are great at absorbing radiated heat so shield them with reflective foil or, better yet, replace them with metal lines that are reflective (silver zinc plated). Treat the lines this way all the way to outside of the engine compartment and anywhere near to the exhaust.
Gonna try insulating with some fuel line heat tube. Also try moving line around. I have ceramic headers so there is a good deal of heat under hood. Is there a safe way of running line outside of inner fender? Could try solid line up to carb.
