I just finished redoing my valve covers and of course I had to remove the fuel lines.Do I need to pull the glow plugs and turn over the engine to get the air out of the lines??
 
Get the ones you can reach easy out. Spin the engine over at WOT. Let off/turn off when you see a mist or it starts to fire. Recall 2 min break after 30 seconds of cranking. Then put the glows in. The primed lines will then help run the engine and purge the rest of the lines.
 
Pulling the glows is unnecessary IMHO. I just did all 8 injs on mine. Just loosen the 4 lines on the drivers side that you can get to cranking it for 30-45 secs, tighten them up and it should kick right off. Hold acc at WOT during all procedure. I just did mine and it tried to start with the nuts loose. Make sure you have two good fully charged batts. These things are not hard to start when in good order. It may sound horribly noisy for a bit while the pcm goes nuts trying to balance out the cyls. A good 20 min drive usually clears that up nicely.
I just started my Burb today using this procedure with no issues.
 
When I've done mine, I'll leave the injector line nuts loose on the left bank. Once I'm ready to start it, crank it over until you see fuel. Tighten the injector line nuts, then fire it up. It should fire right up and smooth out in a few seconds.
I never touch the accelerator, many mechanical pumps go to a full fuel condition at startup by default. Electronic pumps?, I don't know for sure.



You can leave just one lose, it will do the job. The key is to have an escape for the air on the pressure side of the system to allow the injection pump to prime. Once primed and the majority of the air is out of the IP, fuel will purge the injection lines of air very quickly.

That is exactly what I do except I go WOT.
