LPG Tank Hose: Dumb Question

[Citroënbender]

This is not permanently at tank pressure, is it?

I mean, if the hose is ripped in an accident, the tank contents cannot escape via the connected hose used to fill it? I’m assuming it has a check valve at the tank end fitting.

Just checking before I accidentally blow a suburb off the map this weekend.

Correct. Tank has a fill valve inside it. That's the valve that shuts off when the tank is full via a float. It is a check valve.
The fill point also has a check valve that will hold pressure in the line. It can be bled off by pushing the centre bit in with a screwdriver to release the pipe pressure.
Where gloves when you do this as it will freeze burn your pinkys

Thank you. I was uncomfortable just “assuming”, considering the tank I need to remove is still holding about 15-20 litres of gas.
