I find all this quite mysterious... can anybody explain?
Thank you!

A “self bleeding” engine is plastic men’s in such a way that an
electric fuel pump is able to circulate fuel from the tank, through the injection
pump and back to the tank. They are 99% self bleeding, but there are still scenarios that may require cracking an injection line nut and bleeding after the HP pump.
As far as different bleed requirement for different engines.....that’s easy. They were all designed by different humans. Human 1 may design a complete system that has 1 high point and can be bled from there. Human 2ay decide that their design of pump is superior and it requires bleed
ports in 6 different chambers.
