Fuel lines
Hope to fit the fuel tank to my MK Indy-Firblade later. Being in the building trade I have a length of copper micro-bore central heating tubing spare
in the workshop, if I use this with braded fuel pipe for the connections will this be ok?

yes it is, you can also use rubber codan hose for the joins. Make sure you fix it to the chassis with the correct spacing.

technically its ok for SVA, but its also bad for the petrol, copper causes some chemical reaction which does something and blocks up injectors over a
LONG time.
On our cars lots (and lots) of people use it and get away with it without problem. If you're doing huge mileage you may find problems.
No idea what huge mileage equates to, i'd guess (complete and utter guess) 40 or 50k maybe up to 100k.

I did some internet research on this a few years ago - the main problem with copper fuel lines is when you're using low-grade petrol with a
higher percentage of sulphur in it. Over time you get a build-up of copper sulphate in the nooks and crannies of your fuel system.
It doesn't seem to be a significant problem in this end of the world, with our better petrol (Ignoring the recent supermarket cock-up, that
is!).

although my mate who used to design fuel systems for a living had an absolute fit when i suggested it.
He got so miffed with me he brought home some fuel lines they produce for a production car and said "use them and don't kill
yourself".
(ok, there where a few words with 'f' I've removed from his sentence).
edited to add, i'm thinking of using certified rubber pipe - which he'll have another fit over in case there is a fire and the entire
car goes up. Our fuel tanks are also completely unsafe cause they don't have inversion flaps to stop the fuel leaking out when we're
upside down etc etc etc.
(he is a really nice chap and he quite happily pointed out how dangerous all the stuff we take for granted is).
