After looking at my container Im having second thoughts about the creation of a high vacuum.
When the lid is on and clamped tight then the unit is tight...maybe too tight.
Here are pictures of what appears to be a vacuum relief valve on the side. Its hard to see from the picture but there is a horizontal split at the tapered end of the valve on the inside view of the container..
So I question my idea because it might start fueling just fine for the first gallon or maybe just half a gallon before a vacuum is created (like finger over the straw method) and then the valve works but maybe not near enough to maintain good flow. I would simply have to try it first. If it fails then I would simply remove the rubber valve and try again. That hole would be covered from foreign materials but just not sealed. It has to have a way to breath anyway.
Also wanted to mention that if you type in "plastic barrel" or "metal barrel" in Craigslist you might be surprised what you find. If this crazy idea works.
