May be the regulator.
CLOSE the BBQ tank valve
Connect the tank to the regulator and hose.
Disconnect the hose at the BBQ
ENSURE NO OPEN FLAME IN THE AREA
VERY slowly open the valve on the tank.
If you hear a hissing / smell gas, then the tank's valve, the regulator and the hose are OK.
It may be a plugged inlet in the BBQ's or spider nests in the BBQ's vents...use a vent cleaner kit and follow instructions.
If you DO NOT hear a hissing of gas / no propane smell, then it is either the valve on the tank or the regulator.
To determine if it is the tank's valve, close the tank valve, and SLOWLY unthread the black valve connector. You should hear a very short hiss and smell propane very briefly. If you do, then it is the regulator. If you do not, it is the valve on the tank.
Based on the above:
(1# Return the tank
#2) Purchase new regulator and hose.

We are unable to answer your question with the details that are given. It sounds like something is wrong with whatever is connecting the tank to the BBQ. If the tank is full and the BBQs are operational, there would have to be an issue with the connection. We would suggest you y take this in somewhere to be checked.
