need help with AN fittings and SAE J30 r9 fuel hose

[Discopotatoes]

Im about to replace my fuel lines and want to use AN fittings where possible.
Its on a TVR Chimaera which has hard copper and rubber hose running from the tank to the engine bay.
i need to use a good quality 8mm id injection fuel hose which i found here

http://www.flexiducting.co.uk/wp-content/uploads/2...
but the od is larger than the specified 1/2" for -8 AN
and too small for -10 AN

and i can get 8mm od knifer pipe no problem.
which AN fitting should i use on the rubber hose?
