Fuel hose sizes

Hi all.
Need to change all the rubber fuel hoses ( S14a ), did them not long ago when changing metal pipework but poor quality/faulty hose used and degrading already.
Pretty sure I need 6mm & 8mm internal diameter hose.
Could someone confirm sizes please as can't get to car for a while and would like to get new hose ordered up ready.
Thanks.

It's all 8mm (5/16") IIRC

All 8mm, that's good news, only need to buy one roll, which will save me money!
Thanks for that.

Are you replacing the Rubber hose with PTFE Braided hose or with rubber again?

I've ordered a roll of Gates Barricade fuel injection hose 8mm.
