These are two fuel hose types that I installed about 3 years ago. The 13mm hose is marked R6 and branded AGOMA The 8mm is a Gates, made in Turkey, not marked R6.
At the time I was unaware of the 'R' ratings hence fitted what ever seemed suitable. When I became aware, I decided to leave them on and monitor their condition. I'm now glad that I had that, albeit forced, opportunity.
I'd advise checking if you've used either of these types.

Hi Nigel, I’ve been through the same process a week ago on the VX coupe. The smell of petrol appeared coming home from work a week ago and when I got under the car I found damp hoses from the tank. A little squeeze and hey presto. Fuel raining down. All pipes now replaced with R6 purchased from Halfords as I was in a rush to stop the car leaking plus they had it in stock. Let’s see how long these last. When I get home (currently stuck in Italy thanks to cancelled easyJet/Gatwick air traffic control problems) I intend replacing the hoses on the Berlina again as the pipes underneath are around 3 years old and I can’t remember where I got the hoses from. Hard to see above the crossmember. It’s a battle to find hoses that really are what they say they are. Fake pipes are out there.

I'd recommend sourcing them from Car Builder Solutions and going for fuel injection specs, overkill, but the potential consequences of a failure (especially with an electric fuel pump) don't bear thinking about....

Hi Ian
You need R9 not R6
I used Cohline, do not use unbranded, Gates should be a good alternative

My subsequent research indicates that R6 and R9 have similar resistance to ethanol. R9 is indeed rated for the higher pressure of fuel injection which I don't need at present. There is a maybe that later I will fit FI but that would entail reworking the fuel supply to accommodate a rear mounted fuel pump, so I'll put R9 on a future build.
Thanks for all your comments Nigel

Hi Nigel Not sure it is quite that simple. If you read this article the table referring to the various R ratings shows that the R9 versus R6 has a much lower permitivity rating. Also I read that the lining differs between the two which may explain the difference. http://www.volksbolts.com/faq/fuelhose.htm#ProblemsPeter

Hi Peter,
I stand corrected. This appears to be the article I also found but I clearly didn't read it properly.
Thanks, Nigel

As I was in a rush to stop my car leaking on the drive I took a punt and grabbed some R6 from a local Halfords store. I sold it to myself on the basis that Halfords is a big name and surely wouldn’t risk selling fake/substandard fuel hose. It’s rated for e10. I’ll keep an eye on it as always and try to make a point of changing the hoses as part of a service regime every 3-4 years.
Cheers Ian
