I think
@Pappy has a decent idea here. Any local hydraulic or hose shop should be able to crimp new ferrules on a hose. In addition, most large propane suppliers will make hoses too. There is a local Parker store that can probably make something, but they are proud of it.
I’ve seen that photo before, attached to similar claims that it was caused by a gas explosion. I call internet BS on that one. The photo evidence doesn’t match what one would expect from that type of explosion, and the photo taken in a junkyard makes it far too suspicious. I’d have to see proof from a reputable news source, I take pictures of all sorts of mutilated cars in junkyards and you could tell crazy stories for weeks to explain them.
In any event, the hoses we are talking about are removed from the tank with each use, and most of the purchased crap we get from the usual suspects doesn’t have a random failure rate any better than you could do with a Parker crimp machine anyway. I would be more worried about the tank leaking after removing the hose than anything else leaking in storage.
