After doing the conversion work on Randy's Tractor Farm and Family I started looking around to see what was there. I got to say there is a killer way to fix gas can to work.

Good ole American know how.

I can get the valve stems at my local Chevron Station for cheap.

I like this, mike.  I am still using some steel and plastic NATO cans I've had for a while.  Not the easiest as they require a funnel, but they are better than the EPA tyranny.  I still think that steel cans are the way to go, especially as they don't crack and wear out like plastic.  

My problem with steel cans in the rust issues. Fuel out here tend to get water it from time to time and steel cans will rust out. That's what happen to my last two 55 gallon drums was the gasoline barrel rotten from the inside out. The diesel one was more rusted on the outside. So I just replaced them both pretty cheap. I only use the plastic cans for transporting the fuel from the station to the barrel or from the barrel to the vehicle (trucks, ATV, lawn mower etc.)

I saw that video a few years ago and was kicking myself for not coming up with that fix. 

A very simple solution.

I've got a couple of those cans around...cool. Hard to beat the cans that have spouts that store inside the can though.
