I made a fish fryer years ago someone told me to use an automotive grease fitting for the jet with the little ball knocked out. I had that suspended in the center of a two inch threaded pipe about 5 inches long with end cap drilled with 6 or 8 pretty big holes...if my memory serves me seems like the holes I drilled in the end cap were 1/8" at least.
My cooker sounded like a jet engine.
