There are vendors of real, usable fuel cans. They're kind of expensive, but there's a nice feeling of usefulness everytime you use one.

From my perspective there's three options:

a) get an old, plastic can with a vent from the before times

b) buy an expensive NATO metal can, and the flexible spout 'for amusement purposes only'

c) lobby your government to allow gas cans that don't cause actual spills everytime in the pursuit of avoiding fume leakage or whatever.

you can also buy a hunsaker jug... they don't pack as nicely as jerrycans, but they're US legal, have a vent, and i can't recommend them enough. i use them for fueling a 24 hours of lemons race car, and they make my least favorite thing in the world relatively safe and drama free. they dump 5gal in ~20sec or so.

now, if you illegally modify one by adding a legit breather tube... you can dump 5g in ~10 sec or less. :)

How is the rate of evaporation from the old type? I lose gas through evaporation from the new type anyway so they don’t even appear to work. It would be awesome to fill a jerry can with non ethanol fuel if it would last for at least a few months.

I don't think they changed the plastic when they changed the shape, so I'd expect fuel vapor to permeate the old plastic cans too (or at least some of them). A metal can with a good seal doesn't let vapor out, so be careful with big temperature changes.

Ah that makes sense. I can definitely see the pressure buildup in the plastic type. If there is a risk of exploding metal jerry cans that would be quite a hazard.
