The people I got my hose from was a local good motor factors. I have just phoned them and they have some in stock and will post it to you at cost of postage.
Their Part Number is PEA PPH08 ........what they have in stock currently is 7.6mm (which they say will go onto the 8mm fuel line). It has printed on it:
W = SAE J30R9
They sell it by the 5 meter coil at £22.42 (which I suspect is +VAT @ 20% so = £26.90. Thus divide by 5 = £5.39 per meter.

Note: as others have said (including Jim King who has looked up the technical specification, as have I, that SAE J30R6
is suitable.) My last lot from Pat W under that part number was in fact J30R6.
As for length? It was about a meter for carb to return line, so say the same again for supply line to pump to carb....add on the lengths for the rear 2 lines to tank which I do not know the length. The supply/return nylon lines end on the chassis just down below the petrol pump location on my car (GTC).
Suggest contact them by email and ask what they have in..(including what is printed on the hose)..(it can possibly vary depending on their next supply) and get a quote.
