Ralph,
Looks doable - thanks for the pics. The Hayes ought to be a little flatter but I don't know if wider. That might be the limiting factor, the width. I posted dimensions a few posts back, you could check against the width of the Fuji bottle which I assume is square.
Does that water bottle plastic actually hold up to glow fuel!? Alcohol and oil I guess are fairly inert but what about nitromethane?

David,
The gas guys have been using Fuji water bottles for a while now without issues. There's a couple of companies that are making cap fittings for them, I don't recall who at the moment. Also, there's a company out there - Fortitude (spelling??) that's selling complete tanks in various sizes. Info can be found over at F-L-Y-I-N-G-G-I-A-N-T-S.com
