I recently made a flashback arrestor that prevents fire from entering the fuel chamber of a device(anything that requires a burning flame). I would like to note that everything is larger than needed so that users can see how it works. Anyway, without further ado:
Hey, I actually made a Flamethrower and used a Modded version of your Flashback Arrestor. Use solid-only wall to separate fire from gases. I gave credit to you, too!
