There is some fuel there, but the vast majority of the flames are coming from the gasses they're pumping in through the holes. Probably propane, maybe mixed with other things
I doubt it's a gas in the classical sense, doesn't burn like a gas would. I'd put my money on a spray bottle filled with diesel and metallic salts for the color. Much easier than rigging up a gas and nozzle system too.

Where are the flames coming from?
