It depends on how much fuel you plan to store, and how much you use.  I store about 30 gallons of gasoline (non-ethanol, for mowers/generator), and 15 gallons of diesel for my tractor.  I treat the gasoline with fuel stabilizer; and the diesel is treated with Hot Shots (lubricity) and Killem (anti-bacteria).  I don't use my tractor nearly as much as others, so 15 gallons will last me several months.  I store everything in plastic fuel cans, and use a battery-powered pump (Harbor Freight) for transfer.
