I have 1 tan one that was given to me years ago. They are built really strong. Very tuff. As mentioned above, the spout is ridiculous in price. I have not researched an aftermarket one. Ion a side note I have 3 of the water versions and they also are built very well. But I was able to source the correct spout for the water container versions.
They are superior to the European fuel/water versions, which I would rate as the next best thing. My alternative ones are the old 'Jerry cans^ as my backup...backups.
If someone sources a spectre fuel funnel at a good....cheap....price, please publish it....SHARE PLZ....[emoji2]
Again....these military spec containers are stout/tuff.....and we'll worth the cost. No rust issues with there heavy plastic construction I belie bcc e they are the same dimensions as the jerry/European versions....so they should fit mist carriers out there....BUT CHECK IF YOUR NOT SURE.
