Hi daveopam
For many years I used the same steel one gallon can you are using. Then one day I decided that a steel can and a 12 volt battey, or even the 1.2 volts glow driver could be dangerouse. Now I just use the plastic 1 gallon container the fuel comes in. I remove the fuel cap and screw on my cap w/2 fuel lines and I'm good to go and feel much safer. Since I discart the plastic container after one gallon, there is no danger of wearing out the container and causing a problem.
