Here picture of OG brake line pipe of June 1952 Split. As you see, it is steel pipe coated by copper. Similar structure with fuel lines.

Not sure about the purpose of this post. But there was discussion in the past about copper fuel lines. I am of the opinion that a) VW never used copper fuel lines and b) it is a very bad idea as copper is known to "work harden" with vibration. Many planes and pilots were lost in the early days of aviation until this was realized.
Copper plating is another thing, and I think VW copper plated some steel lines for corrosion resistance. _________________ John Henry

My point was exact that copper plating was used to prevent corrosion and if you want to have exact original type lines, you are in troubles. Copper plated pipe source must be hard to find. |

German cars into the late 50's used copper plated lines. These days to reproduce, you bend new lines, copper plate, and install new fittings using a metric double flare tool. Simple. |

I think you guys are in violent agreement here. No one said that VW used *plain* copper tubing, just that they used copper-plated steel tubing to prevent rusting, along with a neato pic. Good idea, methinks!
I've heard that plain copper tubing can also catalyze fuel into varnishing. _________________ 1974 Thing -- under the knife

Yes. I was recalling a thread a while ago about the use of copper tubing for fuel line (some people were making their own, and I think someone was doing repros with it, not that VW actually ever did....). Reading the subject line of Mika's post I see he was just showing us that split brake lines were copper plated. Nothing about fuel lines... _________________ John Henry
