I think this is a good start - very nice effort. However, I think there might need to be some refinement. Every bleed point from the lift pump point up to the low pressure inlet into the injection pump is a low pressure bleed points. The high pressure connections are at the top of the injection pump and the injector ports (on the side of the injectors). I think some pictures are not labeled correctly.
You don't have to bleed the high pressure side when replacing fuel filters. You only need to do that if you introduce are into the high pressure side.
Low pressure points need to be opened until you can see the hole or slit in the bolt on the threaded part. Just cracking them loose will make it much harder to do a hand job. High pressure points should be opened 1 full revolution for bleeding.
You do not need to bleed the high pressure line one at a time. Just open them all crank the motor until you get fuel at each one. Then re-tighten. The fuel will not flow back and introduce air.
