Re-cleaned, rebuilt and tested injector 2 yesterday. Good pressure, spray good enough.
Got everything back together this morning including new return fuel lines and clamps. The transparent polyurethane stuff is great - when I opened up the air bleed screw on the pump, I was able to watch the fuel rise through the return lines and push the air out. I was going to do a compression test, but decided to forgo it since the manual said to do it with the engine warm. I did decide to to a quick check of the glow plugs' current draw and I am sure glad I did. Discovered that the push-button switch installed by the previous owner to operate the glow plugs had stopped working (probably why the tractor didn't want to start the last couple time I had tried). Fortunately, I had purchased a nice 60-amp Grote push-button switch with weatherproof cover as a replacement a while back, so it was the perfect time to install that.
After doing the advanced air bleed, retightening the hard lines, and setting throttle and decomp back to normal, she fired right up. A nice sound to hear after so long. ;-)
Regarding my original question posed in this post, I'm 99% convinced that the injectors for the Kubota D950 engine are the same as those for the Kioti / Daedong TD950. If anyone ever has their Kubota ones out / apart be sure to check the dimensions and nozzle model and let us know.
