Covering copper brake and fuel lines
Is it ok to cover copper brake and fuel lines with a good quality heat shrink tubing?
Just starting building my new Mnr vortx and hate the look of the raw copper.
Had considered braided stainless but decided now to run with the copper if I can cover it up??

It will be covered up by your car eventually
Duratec Engine is fitted, MS2 Extra V3 is assembled and tested, engine running, car now built. IVA passed 26/02/2016

I should have said, is it ok for the IVA and MOT tests to cover the copper?

I don't have iva to worry about but I have done this on my anglia. Used clear heatshrink and you can hardly notice it us there but hopefully
keeps the pipe nice and shiny. Give it a good rub with wire wool or glasspaper before to start with a good shine. I found it easier to put on the heat
shrink before bending, bend the pipe and then heat it after with a hot air gun.
Also worth paying the bit extra for kunifer (copper and nickel) pipe rather than 100% copper, it has a better fatigue life but is a little harder to
bend.

Why are you covering it?

Im putting mine inside that clear braided PVC hose, IF the line was ever to fracture, the PVC would contain it so it leaks out somewhere visible (and
in my case away from my the exhaust) and protects it from grit, stones, rocks etc

Covering it won't be an IVA or MOT issue; Lots of tin tops have sections covered.
I'd have more issue with the fairly large unsupported loop that's liable to vibrate quite a bit. Given that copper pipe work hardens,
I'd worry about it fracturing near the union eventually.
coyoteboy, I think this might be a clue... "hate the look of the raw copper"

^^^^ Yep. You'll barely see it when it's done. tbh I'd rather have it accessible for when you find you need to change it/fix
it/replace it.

The pipes are only roughly formed into place at the min. Once I get them heat shrinked I'll tidy them in a little and make sure there well
supported with clips every 6"
My Mnr I going to be r1 powered so excited about the build now 👍

Had a play with an off cut of fuel line tonight,if it's definitely not an IVA issue I think I'll cover them with heat shrink tubing :-)

How will you ever spot a crack or problem before its a total failure?

You can buy the fuel pipe already covered
If your really bothered about the look of copper brake pipes get yourself a small artists brush and paint them once fitted 
I did it on a 306 Rallye that I re-piped/de-ABS'ed and they did look good

So how do tin tops deal with the fact that it's covered?
Thinking about it, I've only ever had brake pipes fail the MOT where the coating has chipped off exposing the pipe underneath. Is it reasonable
to expect a pipe to last if the sleeve is protecting it (especially if it's kunifer rather than copper?)

Usually some king of steel on a tin top im guessing

That may need some "Royal Treatment" to bend in place...

IF a brake pipe has crack that's visible to the human eye, it's failed and will leak. If it's corroded, you'll see it with
clear covering but without clear covering it's no different to a tin-top, only tin-tops usually use steel pipes and so they're actually
more likely to corrode under the coverings (I've replaced many).
They key is prevention. Support it correctly, coat it correctly and it won't fail, making it riskier but more observable is a bit backward.

A lot of tin tops have brake pipes running above the fuel tanks,so no chance of checking those!

Personally, if I were going to wrap it I'd be ensuring water couldn't get up the ends - seems like a potential water trap location that
isn't needed to me.

I've used heat shrink with glue that melts when you heat it so water can't get in, also my cars not going out in the rain!, haha

Copper pipe isn't the ideal choice for brake lines but corrosion won't be an issue.

Correct me if i'm wrong but heat shrink-ing copper pipes prevents heat from coming IN, or going OUT.......And why some need to keep heat from
going out of the pipes.......However AFAIK brake fluid boils into calipers first.......
Oh, yes - it's looking nice.....
