I think you or others have already mentioned all or parts of this....
Here's how I bled the fuel system of my M1008 recently--with good results.
-- Don't overheat starter by cranking engine too long. You may also have to
recharge batteries depending how long you crank. --
1. Remove glow plugs so your starter doesn't have to fight the compression
(engine will also turn over a LOT faster).
2. Remove hose from injection pump coming from output of fuel filter assy.
3. Put hose in a glass jar, crank engine until you have a good flow of fuel.
4. Reinstall hose onto injection pump.
5. Crack (about 1/2 turn) injection lines going into injectors.
6. Crank engine again until you get fuel at the injector lines. Mine didn't
have a very big flow of fuel here...it was more of a small bubbling of fuel
from around the line/nut.
7. Once you think you have fuel at all injectors, tighten nuts.
8. Crank engine again. If you are getting fuel and the injectors are working
properly, you should see a fog of fuel being blown out of the glow plug holes.
9. Reinstall glow plugs.
After doing all this, mine fired right off after the glow plugs cycled. I also
ended up installing a manual glow plug button.
Without heating the glowplugs, my truck doesn't even think about firing off.
