Got through the SVA OK.
is copper ok or what should i use?
microbore is fine
There was some concern (from a fuel system professional IIRC) that the copper could leach out over high mileages (>100k?) and block the
injectors.
So probably not a real problem for a fun car, and most people have used it without obvious hitches.
I used 8mm microbore central heating tube, and covered it with split convoluted tubing to protect it.

ive seen a lot of rubber pipe perish, so i would personally prefer copper in the long run. Seems more durable.
Apparently the Kunifer pipe is stronger than the usual brake pipe - that's what I used to link my twin tanks.
As said, kunifer pipe is best as it's stronge than plain copper. Also, copper pipe is only supposed (I think) to be single use. IE if you ever
unscrew a union, that pipe should be changed. Can't rememebr where I heard this, so might be complete rubbish.

Just for completeness here is the thread I was talking about.

Usually comes in a roll about 500mm across. As far as I know, if you find 8mm copper pipe rolled up in B&Q, it's microbore and it's the
stuff you need.

Out of interest (and vaguely on topic) - what are the alternatives to copper?
I currently use rubber fuel pipe, but I am getting concerned about the surface cracking I'm seeing, especially at the back where it's
exposed to road muck.
I have seen people with plastic-coated aluminium pipe, but I wouldn't trust alu. pipe for fuel as it work-hardens and is likely to fracture (or
am I being paranoid?)
Braided hose is expensive. Pretty, but expensive.
Can you get plastic hose designed for petrol lines?
David
you can get plasic pipe designed for petrol
just look under a ford xr3i but never found anyone who sells it on a roll
sorry... so copper microbore pipe and whatnot is also suitable for the braking system? i had the notion that it was not allowed by sva or that kunifer
was the only real thing suitable for braking...
people in motor factors here tell me that it's ok to use copper for the braking system...but i give them the eeevil eye

I have used plastic pipe in a Tiger Cat the fittings were basic brass compression fittings and the pipe came from a local (Ipswich) HGV factors
