About ten years back Id had enough of dealing with squat, irregularly shaped leaky polyethylene cans (although they DID have the PRE-CARB spouts and vents), said the heck with it and blew a few hundred dollars on these: https://www.roverparts.com/Parts/GJC20K4
I own four, and TWO of the 10 liter cans.
You can NOT believe how easy they have made my life, storing, handling, transferring gas and diesel.
I spray painted two of em yellow for diesel, store 110 gallons on my farm, use a self-designed contraption of two filters and a pump to polish the fuel so theres nothing in them larger than 1 micron. Every time I go to fill up my truck, I fill up the cans, and transfer them to the storage tanks.
May still buy a home heating oil tank for the same purpose (250-300 gallon size).
Do NOT buy the cheap Chicom crap cans sold through amazon. They dont seal right and the lining dissolves over time. I bought two of em for Kerosene and wish I had just bought another set of four of the NATO cans.
Theyre sold for potable water only, but theyre fine for gas/diesel, even with preservatives/additives.
Buy once, cry once.
Bookmarked.
$154 for four of them. I spent $80 on four of those crappy plastic jugs at Walmart today.
I'd have easy spent double on these solid Jerry cans. Might just do that. Spend money on quality and you only cry once.
