Can you use copper pipe in a fuel system or are there strength/corrosion issues? I only ever read of people using aluminium, SS or mild steel.

I have had copper fuel lines in my Humber for at least 6 years no probs, it was normal up until at least the late '50's

copper was used as fuel lines for alot of cars. it gives relative strength and yet can handle small amounts of flexing. if you want something with more strength go steel or SS. Am going to replace the fuel line from the tank to the engine bay in my 65 beetle. I will be using SS tubing and for the flexible line to the tank i will use SS braided hose etc.

Check the use of copper with the RTA. I seem to remember it being illegal as copper has a tendency to crack if too much pressure is applied i.e. when you jump hard on your brakes. Thats what i was told years ago anyway.

yeh, it becomes brittle from the work hardening and so after a few years maybe you get hard on the anchors and she explodes 😉

yes , it used to be commonly used in brake systems because of ease of shaping & corrosion resistance - but is now illegal in this application, & rightly so, not only was there a danger of cracking, it was easly accidently crushed to almost zero I.D. by accidental impact from a tool or stone or wombat etc

I put new fuel lines through my buggy to cope with the change to a Subaru EFI motor. The Rego engineer I have said a big no to copper. I will work harden and crack, especially in hiph pressure use.
Go to pirtek and ask about High pressure, cold-drawn, Mild Steel tube. It comes in different sizes and is cad plated. It costs a bit, but how much are the lives of ya family and friends worth?

P.s the RTA don't like it either.
