This is to prevent the pressure relief from discharging liquid. So in order to use the threaded AFL fitting I will have to drill out the tube. Also told me that the duo valve with built in pressure relief doesn't have a tail that extends up above the level of gas. So I will have to braze a tail on to prevent it discharging liquid. Has anyone else had these problems? The plot thickens again, I do not think this will be easy as you have siphon tube going down, and you would have PRV tube going up, both on the one fitting, 99% sure you will not get the whole deal into the hole. One tube goes up, one down, 35mm odd hole, not possible IMO, unless you can make PRV vent swivel? ...... Good luck mate, best option, get normal valve angle tank setup.
