Early Big Dog fuel hose sizes?

Energy One
I'm going to be out running some errands today and I'll stop by the parts store and get some hose so I can have fresh lines going on with the cleaned up tanks. On the split tanks, there is 1 tube connecting the 2 halves on top, I'm guessing just a vent line. Then there is the crossover line, it's pretty stiff and I don't know how old, but the fancy looking clamps seems to still be good so I can reuse it. I think I saw that is 1/4"? Then the line coming out of the petcock to feed the carb is 5/16" correct? Am I missing any hoses or sizes?
