I just had to post this. My new John Deere Manual is a GREAT!!!
To bleed fuel injection system on a 3 cylinder Yanmar motor.
1) Open fuel at filter
2) Open the 2 bleed screws on filter housing until no air bubbles
3) Close bleed screws on filter housing
4) Loosen injection pump valves on #1 and #3 cylinders. That is the valve holders on the pump itself. Its the gadget that the injector line attaches to on the pump. Loosen them 1/4turn.
5) Remove all 3 injector lines from injectors, at the injector.
6) Gravity, from a FULL fuel tank, will make fuel fill injector lines.
7) Reattach injector/injector lines once you see fuel at injector. DO NOT ATTACH #2 injector line to injector.
8) Retorque valve holders #1 and #3 to specifications and start tractor. It will run poor because #2 injector is not hooked up.
9) Once you see fuel at #2 injector line hook it up. System should be bled.
This is somewhat different than the yanmar manual I have. Thought it might help someone!!!
