as an engineer cant you see that fitting the adaptor is no more than fitting the regulator . then you are left with the same fitting to fill .open bottle . when at litreage required stop pumping turn off bottle disconect. pay for gas .it is the same gas . children could do it. gas low actually market an adaptor to fit normal bottles to an external filler but it costs more. gas wont burn if you keep flames etc away from it. its so simple. cheers alan.

knowing what and how calor refill their empties...
i have always thought that logically there is no reason why you or i can't do the same.
if you are worried about over fill fit a gauge or fill by weight (scales)
the only problem with doing this on the road is the encounter with the uneducated
