Overall supply line is about 5 meters.

And what do these meters measure? ;-)

Sorry 5 metres in length from oil tank to boiler.

Thanks for responses. I also tried to get soft copper olives as that
is what they use in diesel lines on narrow boats, where leaks end up
in bilges. Nice and squishy to fill the compression joints. As most
narrow boats use imperial sizes, which I suspect is gas stuff.
