Wearable fuel tank for flamethrowers

[Carbadox]

The original idea for this was to have a construction recipe where you would be able to connect a some rods, an oxygen tank and 2 fuel tanks into a wearable, fuel tank frame back slot item that would double the fuel storage capacity of flamethrower as well as maybe adding a cool new way gotcha fuck around with chems (IE, having 2 fuel tanks would split the fuel consumption in two and perhaps finding a new way to mix two chems at the same time). 

However, fearing that it would be abused by chems nerds, perhaps it would be more sensible if an item like that was made exclusive for the firebrand class of nuke ops.
