Later: I just looked online and there's plenty of metric vacuum hose available in silicone. Anyone us this stuff? Apparently it's superior to rubber.
I used silicone hose when I replaced my hose. No problems. I also replaced the hoses on my carbs while I was at it.
I didn't see bulk vacuum hose from Honda when I did mine. Even asked the dealer. They did have bulk coolant hose and I used that on some of the short straight runs as I replaced my coolant hoses at the same time Like Alex recommends. Most of the coolant hoses have bends in them also. I was able to get most of those hoses from Honda. There were a couple that they did not carry, so I just got the long coolant hoses with the bends in them and just cut it to length.
