LOLYou have a pre-EPA gas can and you're not using it for gas?
I don't have any "post-EPA" gas cans... at least, not any that I ain't converted to "pre-EPA" gas cans
Start with these...

You can get them from Amazon, Ebay, and other online sources... I bought a dozen some time back.
Drill a ½ inch hole and pop them in.... done... your can is vented.
Finding and replacing the pour spout (if needed) is a bit harder... but with a little measuring of the required size/threads...

And BAM, no more "post-EPA" gas cans
