      I’m going with 7.7mm (close to 5/16”) for the lot and I’ll see how I’ll get on.

        Let us know how it works out.
        That way anyone else searching for this subject will see the results.

          Yep roger that. It won’t be for a few weeks as I have to wait for mikuni fuel pump and some other stuff to get here. I will advise on progress and trust me if it works for me, it’ll work for anyone !

            I use 1/4" lawnmower fuel line on everything but the petcock and I use an adapter to get it down right after. I think 5/16 will be too loose and will leak.

              Ok I hear you and hands up I’m a newbie so happy to learn as I go along. I raised a query last week and that was the consensus so that’s the way I went. I’ll have a try and see.
              I am in no rush as I think I’ll get this done before I manage to get it registered through UK tax office and DVLA

                your biggest problem using improvised lines will be avoiding sharp curves that may cause kinks that reduce flow.

                  Sure thing but others have done it and if I need to produce a curve I’ll use a spring protector to aid this. I also intend to swop out the fuel pump whilst I’m doing it and looking at some of the illustrations this gives the ability to run more direct fuel lines to the carb and petrol tank hopefully

                      If you need to make a tight bend,just get a stainless barbed U.

                        Just to confirm the fuel line I purchased from David Silver Spares (UK) fits the petrol stopcock and carb fuel line points perfectly.
                        it’s listed as 7.5mm ID is horrendously expensive but you can easily put a 90 degree bend in it without kinking.
