Well there we have it.
A fuel can designed by a bunch of experts who have never used a fuel can
A triangular end means they will not pack into the back of your truck / trailer without a special rack to hold it in place.
A seal that relies upon a gasket of some sort in a rotating housing at the BOTTOM of the tank so when it starts to leak, it will leak the entire contents into you boot , nice.
Being bottom discharge you will never get a build up of water cause it will go into your equipments fuel tank without you seeing it, along with all of thrash that sinks to the bottom.
So the actual container is tough, but what about the release trigger ?
And again a totally unnecessary over complicated device that is both expensive and has very little benefit.
I get flabbergasted about the efforts to reduce unburned fuel being released into the atmosphere.
Go to a park near an airport and feel the grass, it is greasy
Why?
Because each jet that takes off tosses hundreds of gallons of unburned fuel right out the back.
At most city airports that is thousands of gallons a day , each & every day , yet we are worried about a few drips form a fuel can.
Almost as silly as the new fuel lines to prevent the 0.0001% of fuel that leaks through the old fuel lines.
That works out about 1 drop per year.
If there is some one who paints their finger / toe nails, that is equivalent to around 3,000,0000 chain saws, every time the nails get a fresh coat.
