Standard jerry can spout with breather hole and short metal vent pipe to allow air in and contents out. Bubbles away OK but it takes a quite while to empty the can.
Does fitting a bit of tube to the metal vent pipe long enough to reach the bottom of the can speed things up with the can inverted. I can't help thinking that all the bubbling is slowing down how fast the contents can leave.
There should be a breather inside the can already.
That divider in the opening goes to a channel across the top to the back of the can, allowing it to breath. It's an integral part of the (very clever) standard design.
How old's the can? I'm wondering if there's a coating which's breaking up and has blocked that breather channel.
There was an interesting programme on the box, or somewhere, a few weeks ago about the Jerry can. Ingenious design by Nazi boffins. The tale of some being smuggled out of Germany to Hungary & thence to friendlier shores is a fascinating one. Of course the allied boffins got the copying wrong (or decided to do it their own way) but the story goes that the Jerry can helped to win the battle in North Africa during WWII. The inner coating is an integral part of the design. Back to subject. Is a Jerry can the right container for Dave's purpose?
Fairly sure all mine have that but when inverted or even just positioned for pouring through the spout that gets flooded with the contents and the bubbling occurs.
If there was a direct air connection from spout breather tube to the air space in the can I can't but think things will flow a damn sight faster as there is far less resistance to the air getting in to let the contents out.
IIRC the US in particular ignored the design and by associated the British didn't get to see the German container. They used the cuboid fuel can, like this:
These didn't seal poperly and leaked. Eventaully the British got to see the german fuel can cloned it which then had a major influence on the North African campagine.
Primary use is diesel, 20 l is a good quantity to pour into a near empty 90 l fuel tank. It's heavy when full but not too heavy. But it would be nice to shorten the time one has to hold the can at chest height to pour contents into the vehicles fuel tank.
Depends how you're pouring from the can, of course.
When it's near-on full, I'm holding it "vertically", and not tipping it anywhere near 90deg, let alone way past, so that handle-top-corner is the highest point. It's fairly empty by the time it gets to 90deg. By the time it's upside-down, it's to get the dregs out.
If you hold it "flat", handle-top-corner down, then it could well be more of an issue.
IIRC it was a link posted by Harry - one of his "Good" ones (which are often very good), as opposed to his "boring" ones.
That was this one:
