I'd let you know but the ship file has glitched since this morning. That's the last time I ran KSP and now, not only my latest version, but all the last few versions of the Karbonite miner/converter only seem to have the first half dozen parts in them. Mutter, mutter, mutter... I'll do some simple tests and work from there. At least I know that it can be done and has been done before. Thanks. :-) UPDATE: Well that was a bust. Turns out that, while there is fuel crossfeed across the hinge, the Karbonite converter doesn't know about it. That means that whether or not I can get the fuel lines to work is irrelevant. I guess I'l take this over to the Karbonite thread since it now simply involves Karbonite.
