Bleeding injectors

[BCRWL]

How long can it take to bleed off injectors? Engine d750 on a B7100. The middle injector has air bubbles as I bleed. I assume they are from the lines. Bled for just under a minute. The other two don’t seem to have bubbles and bled quickly.
I did drain tank to add new diesel. Bled at filter and bled at the main bleed screw. The decompression lever was pulled as a bled them off.

Do you have throttle wide open?

You need to have the injection system trying to move the maximum amount of fuel.

And it can take much longer than you expect sometimes.

If you can get it to start on two cylinders then the remaining line can be bled with the tractor running if you want to do it that way.

Don't turn it over in 1 minute spurts or you will overheat the starter and have new troubles. I'd try 20 seconds and wait 20 to keep the starter cool.

And like Russell said, patience is a virtue!
