Re: ammo can fuel tank idea
If you use 2 boxes, you could mount them on the sides of a conventional rack, and use one as a fuel tank. If you welded the lid shut after making your fittings for filler and fuel feeds, vents, etc, it should be very durable. Those metal boxes are pretty heavy though, and how much fuel would it hold? 3/4 gallon?
