No Gas Flow

Hi everyone! So I have embarked upon my new adventure of living in an Airstream! Unfortunatly, I was told everything worked but in fact, nothing worked. I've got it all running now except for the gas supply. There is gas in the tanks, but it doesn't make it to the interior...no stove, furnace, oven or fridge. From what I can tell, there is only a regulator between point A and point B...is there something I'm missing or do I just need to replace the regulator?



Thanks,



Gavin
