Another opportunity to learn presented itself. I had modified the plastic 5-gallon can by drilling a 1/2" hole near the handle and pulled a tubeless tire valve stem through the hole so the diesel would flow better. You remove the valve and screw the cap back onto the stem. The diesel fuel caused the rubber valve stem to deteriorate. The valve stem came off leaving a 1/2" hole with a full can of diesel. Fuel can was inside a black truck box. Diesel went everywhere. Another lesson learned. I am currently in Parrsboro,NS and was able to find a yellow fuel can with an air vent.
These user-installable vents are the way to go. Use a 1/2" spade-type wood bit, drill a hole near the top-rear of the gas
can, and use a mallet to install.
Great get-around the modern gas cans that have no vents!
Those look a lot better than the rubber valve stems that I installed and failed. I don't know if pressure can build up in the tank while installed in a black truck box.
I was able to find a 20L diesel can in Parrsboro, NS with a built-in vent. I didn't see any signs of leaking after I got home. I couldn't find it on Amazon. I also put an aluminum cooking pan under the tank with paper towels. It was a mess to clean-up after the valve stem failed as diesel went everywhere.
