Dan, thanks for the comments.
I live in Virginia. To avoid the CARB compliant cans, I may have to have my order shipped to a "free state."
Stein, $60-80 is too much. Expedition Exchange has them in the $40's with a $5 discount if you buy 4 cans. Not mil sup prices but a lot of the surplus dealers are showing out of stock.
Now, the question is poly Scepter or steel Wedco?
A year or so ago, I was looking at cans when gas prices were all over the place. The cheapo cans have a warning that they are not to store fuel for use in automobiles. Is that a safety thing or a contamination issue?
Does Expedition Exchange have the Scepter cans or just the Wedco ones? I was looking for the Scepter ones.
The Scepter cans are pretty indestructible from what I have read. I saw videos of Hummers driving over them and them being dropped from pretty high. They will never rust and won't break your toe if you drop them.
Yes, carrying fuel in vehicles is dangerous. Built in fuel tanks are located so they will not likely be ruptured during an impact, are protected by metal and frame and are not likely to leak into the cabin if they do rupture. If you have a fuel can in the vehicle and it punctures or leaks, you are soaked in gas. I know a couple of guys that had a single 5 gallon can in the bed of a truck, secured. They got in a wreck and it was punctured and leaked all over one of the guys. It ignited him and really did some bad things - months in the hospital.
In an emergency, I would take extra fuel, but not every day. My car holds 20 gallons with a 500 mile range and our Suburban has a 40 gallon tank with a 600 mile range. For everyday needs, I keep a full tank.
