I have now bought this design of gasoline, diesel, and kerosene canister to replace all of the other useless CARB canisters. The flow rate is high, it is easy to control, and the construction stronger (less noticeable swelling and collapsing with temperature). I know the price is higher than other canisters but trust me when I say it is worth every penny to avoid the frustration of other designs

Bought this to haul fuel for our loader tractor, a 55 HP Massey Ferguson with the fuel cap 5 feet off the ground. The only thing I can say is that the California Air Resources Board must really like things that spill fuel all over the place and are next to impossible to use. The first experience with fuel spillage was just filling the can at the gas station -- The strainers that are inserted into the can spewed the fuel back out onto the ground unless one has the fuel dispenser just barely pumping fuel. Using the full container to fuel the tractor was even more entertaining. As mentioned, our fuel cap is 5 feet off the ground, and about 2 feet in from the loader and other support structures. So the instructions about "use thumb on green button to remove pressure" and the "two fingers here" instruction for the dispenser were bad enough, but all of the fuel seeping around the cap while trying to do that little ritual 5 feet off the ground made that approach to using this a non-starter. I wound up just getting a funnel and taking off the cap after doing some minor surgery on it to remove the adult-proof cap lock mechanism. Even then, the lack of a vent hole caused some amount of spillage as the can had to suck in air to allow fuel to be removed. Problem is, there don't seem to be any real alternatives to these fuel spilling, fuel seeping, impossible to use containers.
