Technically, it’s not legal and there are a bunch of rules governing it.I usually load 6 jeep cans in my pickup for diesel. It would be easier to just put a 55 gal tank in my pickup, fill it, and transfer the fuel to my holding tank with a pump. What are the laws in your state hauling diesel? I am in California. Who would have that information? Stan
I used to see the barrel thing a lot but hardly ever see it now.
If you get stopped, it would most likely be by one of the compliance officers, the ones in the pick up trucks. Regular officers seem oblivious of most rules regarding hauling. I had a friend rear ended in a truck and trailer that technically required a CDL (he didn’t have one) but the responding CHP officer never caught the violation.
I have seen officers inspect fuel cans at fuel stations and cite if they weren’t the new compliant cans, you know, the useless ones without vents that spill far more fuel than would normally be vented.
