Unfortunately, a 1000 psi fuel pump would cost a pretty penny which I don't have, and gobble up lots of onboard power, which I won't have.
The solution to this conundrum lies in evaporation. The fuel will dribble out of a nozzle into a "tree" of 3 small stainless steel tubes, which are heated by the combustor. The diesel or kerosene fuel vaporizes quickly upon contact with the hot metal, and the resulting vapor burns easily in the combustor.
I plan to incorporate the "evap" system into the flame tube (the tube somewhat resembling Swiss-cheese inside the combustor which allows the fuel to burn with an even supply of air). For this, I will start with a 3.84" diameter, 3 inch tall "can" with a large hole in the side. This will mount to the end plate of the combustor, feed air to the evap "tree", and support the flame tube, which will fit snugly around it.
The finished ring. I also milled a full circle of the same diameter, which will be used as the top of the can.
Heres the end plate installed back on the engine. Looking a little more complex :)
