Copper brake and fuel lines + rubber fuel hose

[V8NRG]

I'd like to replace the copper brake and fuel lines while everything is off the chassis.

Does anyone know the pipe sizes / fixing sizes ?

Is it worth changing to the copper nickel stuff ?

Also what type of fuel hose have others used to replace the rubber hose sections ?

I have absolutely no idea but the state of the existing lines has always concerned me.

Obviously with the body off it is essential but what is the "shelf life" of brake lines on older cars?

At 15ish years old, if the rest of the car is sound, should we be thinking of renewing the lines as a matter of course?

It always flits through my mind at the end of flat out straights on T/D's, the outcome of failure would be unthinkable .

I think the copper is 8mm ID - the same as microbore central heating stuff.
The fuel pipes have to be fuel specific. I can get measurements if you need them as I have some bits spare in the garage.

Solder 8mm plumbing olives on the end of the pipe to stop the rubber hoses popping off
