Kunifer or similar...

[alan-87]

Morning,

Am currently doing a rebuild on my fury and will be replacing both the fuel lines and brake pipes.

For the long runs I want to use hard lines and the car currently has copper, however I've see quite a few people mention using Kunifer lines.

Does anybody have a good source for this? Or anything similar that is up to the job?

Do not use copper or copper mix lines for fuel, the new E5 and E10 (10% Ethanol) petrol that's coming soon, reacts with copper, better off with stainless steel.

Thanks for the info gents. I have found Bennetts to be the cheapest for the cupro-nickel pipe.

Had no idea about the petrol though so thanks for the heads up!

you need a dogs bks flare tool as well as standard cheapo ones wont flare the stuff as its so hard

I used it throughout on my build, and if I were doing it again, I'd probably choose copper. It's a pig to get the flares right, and they're less forgiving, copper is much easier. So I'd say that kunifer is more prone to leaks at the joints, copper in theory is more likely to fracture after long service, though I've never actually heard of a case.

Just confirmation of what has been said really.

Kunifer is harder to flare and bend and I've never heard of a correctly supported copper pipe fracturing due to fatigue.

Copper is not suitable for use with biofuels such as E5 or E10. You can use stainless steel or mild steel safely though.
