is there any reason why you shouldn't use copper pipe for fuel lines?
thanks Billy

 

Wouldn't be my first choice, can be brittle esp when old/cold, constant vibration might cause a issue ?

i would avoid it on fuel injection due to the higher fuel pressure. carbed are not so much of a problem with it only being a few psi, you can just push a rubber hose over the top and jubilee clip it.
the first and second 205's (1.4s on carbs) had the fuel lines run internally in copper with that twisty cable wrap stuff to protect it. Never had any problems, although the first car ended up on its roof on the second stage the next one only did a handfull of events too lol.
personally i would go for braided if you can afford it, but make sure you get the ptfe lined stuff otherwise you will be knocked out by petrol fumes every time you open the door.
you can get some black cotton braided stuff too for high pressure systems, think demon tweaks sell it.

 

would it be ok to run braided rubber hose underneath the car where the metal lines used to be?

 

Isn't copper used for replacement brake lines? I'd have thought if it was OK for that it would be OK on fuel lines.



Edited to add, it might be Cunifer they use, not copper?

 

i would never use copper fuel lines,too soft and easily kinked,breaks easy and would lose some i.d where you fit jubliee clips.
brake pipes are different as you swage the ends and the soft metal getting squashed makes the seal in the fitting.

 

Iv got copper under my car i made then all my self and made all the fittings and clamps and as im in the air con game i no wot im talking about i 3/8 hard pipe which can take over 41 barr

 

^^^^^Wow mate that is cleaner underneath than mine is on top .

 

Only used it on a carb car but should be ok cant rust thats somthing. ho and mr ST your car if feking mint!!!!!

 

Cheers coley I get some copper in a bit then. Your car looks fookin mint. I should hopefuly have mine running for first time today just need to sort out these fuel lines
