Fuel can pouring and safety - Am I way out of date..?

I was just watching a YouTube video on 2 stroke outboards and when it came to the part that showed the chap filling the outboard from a gallon can, I thought what a great spout. It was push button to start/stop pouring.


With my current tender outboard, a Yamaha F6CMH 4-stroke, the internal fuel tank is too opaque to see the fuel level with cowling removed, there is a filter in the filler hole that effectively prevents fuelling with it in (it doesn't seem to allow air out) and with that removed, the can nozzle/spout goes in but it's nigh on impossible to see when to stop pouring. The perfect funnel I use with my 2-strokes just doesn't fit right in the filler hole (I keep it still because it's got the air holes to let air out whilst fuel goes in).

I was intrigued and a quick search on the internet showed a UK article that mentioned all new fuel cans must come with anti-spill safety spouts.

Watching the video at the link above showed that when pouring into a wine glass, the flow actually stopped an inch or so above the nozzle end. Even that isn't really good enough to prevent me overfilling the outboard.

Searching the web further came up with the NO-SPILL gas system and that looked exactly like the one in the first video. Auto stop, button to pour and what's more, the video below at 2:33 in shows it stopped immediately the fuel reached the end of the spout.


The demo on the weed eater looks like exactly what I need for topping up the outboard.

Am I just way behind in fuel spout technology?

Does everyone else have anti-spill spouts on your petrol cans?

Is everyone else already using cans like this No-Spill with the button and even more immediate stop before overflow function?

Unfortunately, like much else on the internet, that isn't true.

The actual legislation, which came into force in 2014, allows for anti-spill devices, but doesn't make them mandatory. Indeed, it says that they don't work particularly well.

Here's the legislation in readable format - https://www.hse.gov.uk/fireandexplosion/portabable-petrol-storage-containers.pdf
 
I didn't intend to get one of those UK style anti spill spouts - As mentioned in my original post, they didn't look to work at stopping the flow very well in the video.

That US No-Spill one did look rather good.. although the UK supplier only has the spout part in stock to add to a can.

I guess my next thought would be if those US ones meet the UK requirements for petrol storage...
 
My boat is on the hard in the marina in Kuşadası for painting etc. As I was doing a couple of jobs on the boat today one of the marina mechanics was working on a small outboard nearby with an integrated petrol tank. He had a lighted cigarette in his mouth which remained in place as he topped up the petrol tank from from a bottle.
 
Its not anti-spill ... auto stop .... but I have cans that had Windscreen wash fluid in ... 4ltr size. The cans have a spout clipped into the side which you screw on after removing cans cap. The spout is tapered nicely and has air holes to stop the pulsing effect of fuel as air goes back in ... being tapered - I can just see past the spout and stop when fuel gets high.
 
I did like the idea that being auto stop, it should prevent overfill (and thus be no spill)... I also like the idea of a button to press to allow fuel through.

Altgough I've never spilt fuel whilst filling but it always seems rather fraught (and with the potential for spillage), especially on the newer outboard where you can't see through the tank and you can't see into it because of the gauze.

Maybe nobody else worries!
