Re: Jerry Cans - Venting?

God bless you, CaptTom for the link to the source for "normal" spouts. I've been looking for those for months - last week I had to dump my three jerry cans of diesel into the tank because there was no fuel at the marina I stopped at, and we ended up cutting up a milk jug to make an adequate funnel since the CARB spouts will not work on a deck fill. I just ordered the old-style spouts, and I already ordered plain gas caps to cap the jerry cans while not in use.

Re: Jerry Cans - Venting?

* With gasoline, the primary reason for increased bloating is the shift to e-10; the vapor pressure is considerably higher, the boiling point often not much over 105F.

* The best cure for transfer is NOT a better spout, but rather a shaker siphon. Much better than pouring. works with any can, including CARB cans, since you don't use the spout.

Yeah, I dislike CARB cans, very much.

too bad they don't make 'em like that anymore.





they also float when full.


Military cans for the last 30 years are made by Sceptre I think the name is, and no due to CARB civilians are not allowed to have them, only Military.
The NATO fuel cans are very good, I think they are the same as the original "Jerry" cans, their spout is better, two hooks flip over as opposed to screwing in.
Metal fuel cans float when full due to the density difference of I think over 2 lbs per gallon between water and fuel.
I would think steel cans would rust though?

Saw a flyer recently (maybe CTC) advertising "The Vent Is Back" so maybe someone has finally seen the light and reversed this stupid nonsense brought about by some clown trying to make a name for him/herself with the Greens.

Re: Jerry Cans - Venting?

I keep 8 yellow diesel 5 gal containers in the aft cockpit. I've always filled the tank at sea from these containers. I lock the twist valve on the spout, tip the can upside down into the fuel filler tube, the valve opens automatically when the spout is inserted, fuel flows without any spill. I had an old style container and hated it because the finger over the spout trick doesn't work well when the boat is pitching and rolling. I gave it to a guy who preferred old style to modern containers.

RE OP post, I have no problem with oilcanning on the cold N California coast whether containers are full or empty.

Before I learned how to use the spout I used a shake siphon. It works but it is slow.

Re: Jerry Cans - Venting?

why would you want to vent them? Afraid they will burst? Never heard of one bursting though I guess it is possible. venting is losing fuel and adding garbage to the air. Build the cove as was mentioned or paint it white.

don't believe everything you think

Obviously, the fire code and OSHA require gas cans to be red and diesel yellow. But above ground storage tanks are required to be either white or silver to reduce heat gain.

White paint would also reduce UV damage.

Interesting. Of course, getting paint to stick to PE is also a problem.

Re: Jerry Cans - Venting?

I too have had this issue where the can expanded so much that the plastic cracked! Keeping them out of the sun definitely helps prevent the bloating.
