Have you ever tried pouring five gallons of gas into an automobile?
I have the Blitz cans, which don't even have multiple handles.
Your arms practically fall off before the gas finishes coming out
of the glug glug spout. And I'm not a little guy.
Nope. What I do is dispense with the spout altogether and just siphon
as needed. It takes just over 4 minutes with a ten foot 1/2 inch ID
vinyle hose to empty a 5-gallon can, with the can on top of a towel
on the roof of the car.
Then, it takes another 30 seconds to get all the last drops out into
a funnel into the vehicle's gas tank, because whatever you leave in
will expand to 22psi (IIRC) which, since the cans definitely do not
leak, will bloat the thing like a beach ball in the hot California
So, I leave the nozzles loose for empty storage, so all that gas vapor
won't bloat the admittedly otherwise airtight gas can, trying to get as
much liquid out into the car as I can.
No, I haven't and for the exact reason you give.
Using the plastic 5 gallon cans with or without the screwed up spouts,
it's not all that difficult to fill the Bobcat's tanks as they are at a
convenient height and provide easy access to the fill neck. AAMOF, of
late once I get the first gallon into the tank from a full can, I just
set it down and remove the spout altogether. With the installed valve
stem vent open, I just pour it into the tank without a funnel. The
angle and the wide mouth filler neck make it a snap.
As for him that said he pours out five gallons in 20 seconds...
Bullshit! You couldn't empty a five gallon can on the ground in that
time let alone into a fuel tank.

I sometimes pour gas into my riding mower without screwing the spout on,
but it pours a lot faster with the spout. Head supplies the energy to
make a liquid flow. With no spout, I have a fraction of an inch of
head. With a 10" spout pointed down, I have several inches of head.
If I were to pour the gas into a funnel, I wouldn't have much head in
the can or in the funnel.
Head supplies the energy to accelerate a liquid. Accelerated to a given
speed, 4 times more will flow through a 1" opening than through a 1/2"
opening. You can dump a can fastest if the spout has the largest
opening that will fit your tank.
Turbulence slows flow. If a spout is tapered, being as wide as possible
where it fastens to the can, it will cause less turbulence than a
straight tube. Corrugations will cause turbulence.
Viscosity slows flow. If I entered a gas-pouring race, I'd let the can
get hot in the sun before pouring.

That's exactly what I do when I store the five gallon gas cans
If I screw the spout on tightly, as if the can is full, the
twenty-something psi bloats the can like a beach ball.
So, I too, leave the spout on loosely when the portable storage
container is empty. I do try to get all the liquid out when I'm
emptying it though, as there's no sense polluting more than we
have to to live with the idiotic design of these gas can spouts.
As I said before, the solution is to find a good gas cap, which
solves almost all the problems almost instantly.

Legally, in California, you can carry up to 600 pounds (yes, pounds) of
hazardous materials in your car (or truck) without needing a special
permit. That's more gasoline than you can carry.
In NY, I believe it's 25 gallons, which is less gasoline than you can carry.
I can carry about 50 gallons in my trunk, for example.
A couple of weeks ago, a hospital security official informed police he
suspected a man of having gas in his trunk. They went for a warrant.
The judge said if they suspected gas in a trunk, it was a public
emergency and they didn't need a warrant. They brought their
drug-sniffing dog, and he alerted. That guy's in big trouble now!
I've read that if you carry gas in a trunk, you should leave the trunk
open and not combine that trip with other errands.
I put my can on the pavement before filling. If it's on the mat in a
truck bed, a spark could jump between the nozzle and the can.

Probably because they're not airtight?
I've read the spec, but it has been a while since, so, what I
remember is that it can lose almost nothing (in ounces) after
so many days at such and such a temperature outside.
The one I had was airtight. The vent was a tiny hole just above the
threaded hole where the flexible metal pouring tube screwed in. When you
screwed on the steel cap, it sealed everything with a rubber washer. I
felt secure against leakage.
Plastic cans used to allow some of the volatile stuff to permeate.
Whether or not this was a pollution problem, the fuel wouldn't be as
good in the future. CARB cans are treated against permeation, I believe.
I siphon all the time, as the wife hates to fill up at the gas station.
It takes me about 4 minutes and change to empty five gallons off the
roof of her car, but I use a ten-foot clear hose, of about 1/2 inch ID
and use mouth suction.
Every once in a while, it gets me.
I've learned a few tricks, such as having three hoses so that I can do
three five-gallon cans in sequence without breathing in any vapors.

Since I carry 50 gallons of gas on my trunk all the time, and, since
I've checked with the fire marshal & OSHA regulations for storage,
and since I've checked with the CHP for transportation, I was
surprised at what you wrote ... but ... if you read the article,
you find he had completely assembled molotov cocktails in his car.
In addition, while you mentioned the "hospital security official",
you didn't note that the perpetrator was a patient in their
psychiatric ward, who had expressed “homicidal tendencies”,
according to the article and that a crossbow was in the car
in addition to 25 molotov cocktails.
So, I wouldn't exactly characterize what the police termed
"entirely assembled molotov cocktails" on the same level as
someone transporting 10 five-gallon cans of gasoline in approved
I wouldn't want to carry 50 gallons of gas in my trunk in consumer cans
all the time. I'm sure no trucker would bump my trunk on purpose, but
plastic cans may deteriorate and crack. It reminds me of the line from
Young Frankenstein: "A riot is a terrible thing once it gets started."
I wasn't aware of it, but some military jerry cans were plastic. The
National Forest Service, National Parks Service, and Bureau of Land
Management, have prohibited the plastic ones since 2012 except in
saltwater environments. They specify metal jerry cans meeting
specification UN 3A1. For transportation, they recommend replacing the
self-closing lid with a bung.
I'll put that on my shopping list.
Hey, I remember the guy with the nutty wife story.
Seriously, instead of enabling nuttiness, you should be
doing something to stop it.
50 gallons of gas is around 400 pounds. That does wonders for
your gas mileage, and is seriously dangerous. We just had a woman
die in NJ, partly due to gas fumes in her car. Those cans can easily
rupture in an accident.

Transporting gasoline in anything but DOT approved container or the
vehicle gas tank is a violation. That is why that NATO can was
illegal. It is not a DOT approved container ... and probably not red.
I had a guy screw with me once about putting gas in a diesel can and
that is the same can, just yellow.

A kid got bitten by a mountain lion last Sunday here in the Silicon
Valley. A truck ran over 11 cars, and killed one guy on highway 17
about a month ago. There are something like 22 murders in San Jose
Life was never perfectly safe, but, still, the chance of blowing up
in an accident, while it is non zero, is probably less than that of
getting bitten by a rattlesnake out here (which almost happened to
me just last week).
Besides, if it's any consolation, Myth Busters had a devil of a
time blowing up a Cadillac. IIRC, they had to resort to incendiary
bullets, and the spilled gas wouldn't ignite from a cigarette.
Of course, gasoline vapor *does* explode, but, luckily, the cans
*do* seal the gasoline in pretty well, so, given I'm at retirement
age and I've never had even a fender bender in my life, the odds
are pretty good that I'm not going to get into an accident on my
way home from the gas station.
People who are that afraid, by the way, shouldn't drive, just as
if people are that afraid of poison oak, ticks, west nile virus,
ebola, rattlers, black widow spiders, etc., shouldn't walk outside.
"So, Mr. D, we are here from news team 4, following
the story of the man who drove home and didn't have
a fender bender. Would you please state for our viewing
audience what it was like to get home, and not have
your car towed?"
Is there some Department of Transportation regulation that requires gas
cans to be red and the corresponding cans for diesel fuel to be yellow?
It does occur to me that every Wedco plastic gas container I've ever
seen has been red in colour, but it never crossed my mind that it was
SUPPOSED to be red.
And, is there any reason for this?
