I had the hose on my turkey frier burner catch fire at Big Brew last year when somebody moved my tank, pushing the hose up against one of the legs of the burner. The rubber melted and it flamed up. That was a scary moment. A buddy turned a hose on the the flaming hose while I closed the valve on the tank.
I was able to get the hose replaced for less than twenty bucks. Even after you get your new burner, getting the hose replaced will increase your options.
