To anwer your question what's inside.

It's little tubes in a ring, about 1/16 diameter. The fuel enters the engine, goes straight down to the back near the turbine blade and splits off at a T into a circle around the Circ of the engine. Every CM or so, there is another T that comes forward towards the front of the engine.

That tube comes to a point where you have basically a hypodermic type needle. Where the fuel is atomized into the comb chamber.

Those tubes are far too small to be pushing liquid through at the exhaust of the engine and get anything worth while. They are really tiny.
