Great video Nick. One of my favorite Christmas decorations is an ceramic Christmas Tree a little bigger than that one. Came from my dear old Grandmother may she rest in peace.
First time I've noticed your flexible tubing hook up to your Bix burner. I'll have to do the same.

I have a couple of those ceramic trees too from Grandma... a big one that takes a full size lightbulb and a miniature that has a little candle looking bulb.

I’ve used silicone fuel line on my gas burner for right around 10 years now with zero problems. I have had many say it’s wrong over the years, but using a little common sense, I don’t see the problem. If for some reason it developed a leak, it would simply burn a few seconds till I shut the gas off... If the hose wants to tip/pull the burner over, simply twist/rotate the hose a little bit on the pipe and it will no longer be “pulling” on the burner
