Jerry Cans - The secret Weapon

Two things that I'll suggest. Use a tough coating on it. Like POR-15 (with a UV resistant top-coat) or "Rust Bullet" or similar. The prep for these coatings is absolutely crucial to do exactly as they say to do it. Make sure that it can't move even the slightest in it's mount.

I use ratchet straps to hold mine in place. I buy inexpensive ones, cut them to length, and expect to periodically replace them. On one truck I bought a Mac's Tie-Downs 1" ratchet strap and am testing to see how long it lasts in the same use.

I have a Wehrmacht jerry can stamped 1956 that I still use. Yes, I repaint it from time to time, but that's easy maintenance. I'll bet there will be zero RotoPax containers still in use in 2085.

I did have a failure on one Wavian can that had been consistently clamped down too tightly and eventually developed a hairline crack. I recycled it (another distinction from RotoPax), but if necessary I could have had even that repaired.

We love our 38 gallon tank on our '19 Tundra double cab. Having a 300 mile plus range is mighty convenient and helps with the peace of mind. The instrument panel says 410 miles range when filled -- but if you think I trust that -- no way!

x3! It’s been a game changer in Baja. 

What a great thread. Never knew there was a high quality alternative to those leaky Blitz cans (threw mine away years ago). Although I have two tanks in my Toyota, bought a 5gal Wavian as extra insurance for an upcoming Baja trip. Was showing it off to a friend who goes to Baja regularly and he said last time he crossed the boarder they were confiscating any cans that had fuel in them. Apparently they were claiming that was gas smuggling and they had a whole pile of confiscated cans. I guess if you want to keep your fancy NATO cans you’d better wait to fill them until south of the border, I know that’s what I’m going to do. Anybody else heard about this?

I thought it was more of a way to get you to purchase fuel in Mexico. 

Love the quality of my new Wavian can, but disappointed in the included spout. Was only able to empty about half the 5 gallon can into my Toyota due to the angle, and it took forever. 

Would  like to get one of the Swiss spouts mentioned earlier in this thread, but link shown was out of stock. Anyone know another source?

Not that I know of. I had to check periodically to get mine.

One thing to note is that those Swiss nozzles need an adapter to work with an unleaded fill neck. I don't know of anyone making such a thing. I've made the one that I have from 3/4" copper pipe and some fittings. With just a little sanding the 3/4" copper will fit thru the opening in the fill neck. A friend made his adapter from some sort of reducer fitting so that the end of the nozzle fits inside the large end of his adapter. Mine isn't so elegant.

Use of the adapter has had no observable impact on the speed of emptying the can.

I use the shaker hose. No need to hold that heavy can. 

I do the shaker hose thing too. I put the can as the shelf I made for the dog and it dumps the can in about 3 minutes!

The shaker hose that I bought needs an unleaded adapter, so I've never used it.

I've never timed it, but I'll estimate that the Swiss nozzle takes about 30 seconds to empty the can. Maybe 45 at the most. I don't particularly like handling fuel, so the faster the better, even if I'm not in a hurry.

The secret of the Swiss nozzle isn't the size of the spout. It's in how it vents the can. I'd venture that any nozzle for these cans could be as fast if the vent assembly were reverse engineered and applied to the other nozzles.
