Copper work hardens and will quickly crack from vibration. I'd hate to see anyone torch their vehicle from leaking copper fuel lines. :- Joe Even something as simple as a fuel line of copper wound around a section of upper rad hose ,and insulated, might do it. Perhaps the Peugeot already has a fuel preheater, but even so, it might be worth trying another just to thin the bio out a bit, after you have confirmed that it is bio from a virtually complete conversion. 3) Run a blend is always an option.

Re: [biofuel] Lucas diesel pumps
I don't understand the problem with using soft copper for fuel line, just make sure it's secured obviously. If you didn't know, diesels use steel for their high pressure lines.

Re: [biofuel] Lucas diesel pumps
Martin, the problem is not the soft copper but that soft copper becomes 'hard copper' after some time. Due to bending, pressing and vibration the copper hardens and becomes brittle (much easier breakable then mild steel). Nevertheless it can be 'softened' again by heating it up to 'color changing' temperature. This should also be done on copper 'gasket' rings (oil drain plugs) before reinstalling. And Ed.. well if the lines are in fiberglass or firm mounted, so that no open swinging is possible, that's ok. It wont break until you try to bend it. But if you just coil it open around exhaust or make similar home made constructions, then the lines will swing and eventually break.
