S2 fuel hose bore size?

[Peter M]

Hi,
The fuel hose connecting onto the pressure regulator is cracking and needs replacing. What bore size hose is correct?
The pressure regulator says 3bar so I presume the standard 20bar rated E10 hose is suitable.
This also suggests the complete hose system needs replacing at some point.
Thank you

8mm or 5/16"

a lot of poor quality hose out there, careful what you buy!

Gates "Barricade" about as good as you can get.

Another vote for Gates Barricade, the only one we KNOW works. The whole system doesn't need replacing, just the flexible hoses.
