Kitt will be coming off the road at the end of the month for some needed resto work and an upgrade to tpi.
the fuel lines from the donor are a bit rusted. Would braided stainless lines from the tank to the engine be safe and legal? I see from summits website that the lines with an fittings can handle a few thousand psi?

Also would they work on brake lines too? Or should I use solid lines like stainless or that copper/nikel stuff.
thanks

they would be safe and ok for MOT as long as they are secure
this could be your only headache, and where rigid pipes are better as they can be bent to shape and clipped in position
for brakes, hoses would need a lot more securing and though they are better than standard rubber brake hose they still stretch a bit so you will find the pedal will feel a bit spongy

So maybe a no for the brakes. I have no idea what the brake lines in the car are like. I hope they are fine.

I've done a few searches and it seems copper/nickel are better than copper, I think it is called kunifer.
could that be used as fuel line instead of the factory steel kind?

normally use the copper pipe sold at plumbing and heating suppliers intended for oil boilers (from the tank)

I used braided brake lines from master cylinder to front brakes on mine,as John says,i had spongy brakes so went to hard lines with braided from chassis to calipers.
I used 10mm and 6mm copper pipes for fuel,bought it off ebay.3rd gens might be a different size though.

I've been having trouble finding the correct end fittings/unions for the fuel lines. except some ebay seller wanting £15 each lol.
Every time I search I find fuel fitting to AN adapters, so at the moment it's looking like the braided fuel lines is going to be the easiest option

Might be easier to get them if you know thread size of what they are going in to,fuel pump etc,this guide might make it easier to work out.
