What is the first thing to look for when buying a used flamethrower?

Question

Is there a section I should be checking for stress or cracks?

Follow up question, What would be the difficulties of hunting with a flamethrower?

Answer 1

Make sure no residual fuel remains. Pump it up and submerge it in water to check for leaks. Then make sure the igniter flints are available for the particular model.

Now the only difficulty I had hunting with one was the hunted were shooting back most of the time and I had to make a circuitous route to the target to avoid perforations in the pressure vessel.

Then after all that, and a couple of concussion grenades, you are never sure you hit the target.

OOPs, I forgot the other difficulty, the thing weighed 125 pounds.
