OEM Japanese Fuel Hose
Honda seems to use the "red stripe" fuel line. This can be found at Sudco's site. They claim it's made by Kitaco (Kitako seems more likely) in Japan. It's available in 3.5mm, 5.5mm, 7.5mm, and 8.0mm inside diameters.
Sizing
Sizes are generally given in terms of:
- Inside Diameter (I.D.)
- Outside Diameter (O.D.)
- National Pipe Thread (NPT)
