Brom - How much would a Fuel rail and all hoses to do a Saph Cossie be?

I might take the car to 550bhp so need whatever size that needs (-6 or -8?)

I want to aeroquip it, but don't know what to order seperately so thought it would be best to order all of it from you. I have an 044 pump, so need an adaptor for that, then the hose to the rail, the rail, my 4*4 regulator, then aeroquip line for the return, plus whatever unions / connectors go with that lot!
