Hi, Gary,

I got most of my sundries from Car Builder Solutions.  Good catalogue and website and next day delivery (without fail during my build).

Yes well aware of CBS, I have already checked their website and they don't sell Steel fuel lines unfortunately

Why not use copper piping ?

Was not sure it is acceptable on fuel?

Or frowned upon at IVA test?

I Would recommend cunnifer (kunnifer ?)  rather than copper. Copper work hardens and is then prone to cracking. Not ideal for pressurised fuel lines.

cunifer is an alloy of copper and nickel, usually with a bit of iron as well. Hence the name. It is supposed to have the benefits of copper, but without being liable to work harden with flexing and vibration. And unlike mild steel isn't liable to corrosion. 

It is used mainly for solid brake lines.

Agreed it is more commonly used for brakes but i'm assured its fine for fuel and I couldn't do this with steel very easily:

Personally I would use Kunifer rather than Steel for both brake and fuel lines.  as well as being easier to bend by hand and using DIY tools, flaring the ends for the flexible fuel pipe and unions requires a lot less effort or specialist tools.

Thanks

On the fuel lines would you double flare the ends to make a ridge for the rubber pipe clamp to rest against?

If the lines are 8mm, you could fit compression olives like this trick:

Yes, that or use Mike's compression olive trick. The last thing you want to have is a fuel hose popping off :oops:
