Gas Can Issues

I do the same as @Alaskan_TA for a vent. Valve stems are cheap. Just take the stem out, run a coat hanger thru the 1/2" hole you drilled till it goes out the fill hole. Run the wire thru the valve stem, and pull it back thru the gas can. Pop it into the hole you drilled, screw the plastic cap back on and your done! Also, you can buy replacement free flow nozzles at Tractor Supply. The label says they are for "water" jugs! :D
