I applaud your foresight to store fuel before an impending disaster. Sadly, very few attempt this until it's largely or entirely too late to do anything about it.
The key to storing gasoline correctly is simple: keep its container absolutely air tight until you're ready to use the gasoline. I've kept regular ethanol added gasoline like you see everywhere (i.e. E10) stored this way with no stabilizers or additives for over a year on multiple occasions and burned it in multiple engines with no problems whatsoever. Many others have as well. If you were planning on storing it longer than a year, then a stabilizer is a good idea. Stabil is alright, but PRI-G is far superior. It's available at Amazon and other online retailers. Just follow the directions. The only time you would open your gasoline container apart from immediately using it is to add PRI-G once a year.
I would never advise anyone to store gasoline in a 55 gallon drum for two reasons. First, if anything happens to the gasoline in that drum, you now have no fuel, unless of course you're storing multiple 55 gallon drums. Second, once its full, the gasoline alone will weigh 341 lbs. There's no way you can move that anywhere should the need arise (i.e. bugging out, house catches fire).
There are three great and easy ways to store gasoline for extended periods of time. First, the standard red five gallon plastic cans you see are made out of high density polyethylene (HDPE) and store gasoline perfectly well. These are very portable and easily moved by any healthy adult.
Second, you can get 15 gallon HDPE drums to serve the same purpose. These are generally even more durable than the five gallon cans and can be sealed up tighter than just about anything else with a good bung wrench. When full, they weigh about 100 lbs.
Third, you can use military jerry cans. These are metal and are more durable than the five gallon HDPE cans, but they are also much more expensive. If you are going to leave a fuel can in a moving vehicle or any other situation where it may be jostled around (it should be secured well, but still), then this is the best choice.
I personally use both five gallon cans and 15 gallons drums for my gasoline storage.
Forget using the stupid EPA filler tubes. They are a pain to use and can break easily. To get the fuel out is easy and requires no motors or pumping. I just lift the container a couple of feet higher than I what I'm filling and use a siphon hose to siphon the fuel. 3/8" fuel line that can be bought by the foot at your local auto parts store serves this purpose very well. You can get a quality siphon hose bulb from the same store most likely or certainly from a boating store. I like 5-6 foot lengths both above and below the bulb.
For my five gallon cans, I use some simple base caps that I got from a website called EZ Pour. They work very well and make the whole setup more compact and durable.
As noted above, check your local regulations to see if there are limits to how much you can legally store. There are none in my area, and my home insurance agent specifically said that I'm covered even with my stored fuel. I suggest you check on this as well.
