Just a few thoughts on this conversion.
Glow plugs..the 2.23 uses 6v glow plugs I believe. If you wire 12V directly to them with a switch, they will burn out. Be sure to use the resistor setup. (I burned a set up jumping directly to the bus bar.

Fuel filter..If you are going to run veggie in it, you might consider using the filter off the diesel Tempos/Topaz/Focus from the 1986 area. These had a heater in the filter. I have seen several of these in junk yards.

Vacuum source...Also, off the above Ford (Mazda) engine, they had an electric vacuum pump which was mounted down between the bottom of the radiator and engine. I know there are other electric vacuum pumps on the market.

Just some thoughts.

Good Luck,
Max
