This also only applies to US only apparently. Yet they still advertise as if it's an overland product, designed to be used for the most obvious case... Check
their Instagram.
This is pretty much our exact case. I'm not sure what else you would be pouring into the fuel tank? What's beyond insensitive is that they posted this AFTER knowing about what happened to us.
Here are more examples (click the links) of their advertising for this product.
One , Two , Three , Four , Five , Six (this one is a video)
There's a good chance these links will be taken down soon but I have videos and screenshots of them all.
It seems it started out as a Fuel Bladder so I can only assume something happened in the US and they changed the name of it. They clearly know they have a product that could potentially harm people, yet they continue to sell it...
We actually really liked the product initially and were talking to them about helping to spread the word as it was easier to use than jerry cans and folded away. We were very clear about what we'd be doing with them and what conditions we'd be taking them in and they were all for it. I would never normally do this but I feel we now have a moral obligation to ensure this doesn't happen to anyone else. We couldn't live with ourselves. It's a real shame as I'm all for innovative products but when we're talking about the transport of fuel and people's lives, you can't cut corners.
