As you say there are plenty of suppliers with R6 stating it is suitable for unleaded?

I'm resurrecting an older discussion about Fuel Hose specification and suitability.
Researching for E10 fuel (petrol with 10% ethanol) I came across this interesting post....

Now that got me thinking about the future IVA test for my Royale Sabre. It's not clear when E10 fuel will be introduced into the UK and the German government seems to have botched their introduction which may delay the UK introduction. You can carry on using super unleaded but that is only going to get more and more expensive.
I think the IVA manual only says that the Fuel Hose has to be 'suitable'. Copper is not compatible with E10 (as it corrodes) so my conclusion is that I should be fitting SAE30R9 rubber hose all the way from my tank to fuel rail.
(My IVA is probably 2 years away by which time E10 may be common)
The trouble is finding a supplier of a premium branded SAE30R9 hose.
But I think i've found a supplier today. I'll speak to them in the next few days and see if they are happy to supply direct to the public in small'ish quantities.
