Smell of gas in van ⚠️

Yes he said it leaked 4 litres in a liquid state but he didn’t say it remained a liquid after leaking. I read it to be a way of quantifying the size of the leak, not a comment on what remained after the leak. He went on to say that was about 1000 litres in vapour form. A leak in the filler hose would initially be in a liquid state because this is how it is stored and pumped.

exactly. User may've filled with 16L of LPG when tank capacity is 12L - ergo 4L escaped in liquid form.

I hate to argue with you but, that simply isn’t possible. Propane boils at around -43deg C and even butane boils at below 0deg C!
I’ve no doubt there was a leak but, it simply could not be of the scale you refer to, unless in the Arctic/Antarctic!

It’s completely possible and exactly what happened ?
Customer pumped 4 litres of liquid state LPG into the void between the outer and inner skins , this will almost instantly turn to vapour and produce approximately 1080 litres of vapour.
He knows it was approximately 4 litres as he was surprised that the pump slowed but he continued filling
Van was full of gas so he opened all the doors and vented as much as possible, he came to us the following day.
I think you have misunderstood my post .

Basildog in his OP said that the vehicle was presented to him with 4 litres of liquid LPG in a void, with photograph, so it had not gassed off by then.

And that simply isn’t possible, at anything like ‘normal’ temperatures!

I thought my explanation was obvious
Otherwise we would be selling LPG by the bucket full

I think that some of our confusions emanated from the original post stating 'presented' and going on to say 'in liquid LPG', without explaining that the leak was the day before being presented.

Not criticising but just getting to why there was some confusion.

Noted several posters say LPG cannot be liquid at atmospheric pressure. Depends whether it is dispensed faster than it can evaporate. Had 'fun' on a fire safety course with an open (metal) bucket filled with liquid LPG: 1. freeze something [note OP's photos show the ice crystals]; 2. ignite surface, burns slowly (and invisibly) due to limited oxygen supply; 3. knock over bucket, fireball!!

Yes I could go into detail about some of the things you can do with LPG when needs must , but here is definitely not the right place for that
