Message Specifying burst rating and working pressures, among other characteristics. The SAE J30R9 standard doesn't dictate a size. Though because it is an SAE standard and not a DIN or ISO standard, it may reference various sizes in inches, not in SI units.

SAE J30R7 is hose used for low pressure carbureted systems. With a working pressure half of what the R9 is rated for, it is dangerous to use with fuel injection applications.

I've said it six billion times before, but apparently I'm only saying it for my health; Nissan OEM fuel hose is best for the Z32 with standard fuel system fittings. End. Fin.
