Any idea of what it looks like because I am currently cleaning out a retiring mower guys stock and he was talking about working on a twin but don't know if a tank may be among all the bits in his sheds. I bought one of those things new and it only lasted a couple of cuts before it wouldn't start. Victa agent put a complete new engine on it under warranty as it was cheaper for them to do that than try and fix what apparently was a design flaw in the first of them, but it was a long time ago and can't recall what the fuel tank was like.
