I have a T25 Westy 1980 with the twin hob and 3 way fridge.
I have installed a gas bottle and UK regulator, and with the bottle on there is definately gas at the first union, after that union there are 3 taps, with three outlets to the hobs and fridge.
Problem is, I can't get the hobs or the fridge to light, no matter what combination of tap on/off position I use. Its liie a friggin rubiks cube trying different settings.

Can anyone help with which position they should be in, and any advice?
Thanks in advance.
