OEM Japanese Fuel Hose
Honda seems to use the "red stripe" fuel line. This can be found at Sudco's site. According to Sudco's site, it's made by Kitaco (likely a shortening of Kita and Company) 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)
- Air Force Navy (A.N.) (typically for brake systems, not fuel)
Tank Outlet Size
Most Hondas I've seen use 3/8" NPT outlets on their tanks. Some bikes use custom adapter plates. Later Honda CB750's use what appear to be Harley-Davidson style, 22mm outlets.
Tank Capping
Most gas tanks can easily be capped (for de-rusting, Kreem coating, etc) using a simple, 3/8" brass NPT cap (note: not a plug, which is male-threaded). These are available at most hardware stores or from McMaster.
Fuel Hose Size
Honda fuel line seems to always be 8mm inside diameter (just over 5/16", which is 7.9375").
