Fuel line and vacuum line size

[Nelsonmd]

I dont' know the sizes specifically, but I just get the closest thing at the parts store and that seems to work. the hose clamps don't always fit on depending on the wall thickness, but now I have all my lines as black fuel line (I had some thinner clear blue fuel line before for my vacuum line and it didn't really hold up), and in whatever english sized the part store had. I do need to get some clamps for them, but honestly I wouldn't worry about getting the exact right size.
