I acually have already went and bought 2 MSR 20oz fuel bottles and attempted to clone your tank idea. I failed on every level and they leaked and was generally a mess. I still dig the way it looks though. I might give it another go but for now I'm looking at a rear mount keg style like on the sportsman site without the $150 price tag. For now imma make due with what I already have on hand (1gal penut tank) and as my funds increase, ill buy what I really want. I have been looking at various tanks for about 8 months and haven't found the one that's "just right"
