he procedure we used was like this:

One guy cranked the engine while the other slightly loosened the fuel line
nut until fuel started squirting out. You could see the air bubbling out
as
well. While still cranking the engine, we'd re-tightened the nut, then
we'd move on to the next cylinder. Like I said, it took several times on
each line to get all the air out so the engine would stay running. In
fact, we killed the battery and had to take a break while recharging it
halfway through the process.

There may be an easier way, but neither of us were diesel experts. It
worked though.

I have a Mercedes Unimog. When I ran it out of fuel and got air in the
lines, I cranked it till it started. About one minute of cranking and
it started and ran bad. Gradually it smoothed out as one cylinder
after another acquired an air free line.

Apparently some diesels will self purge and prime, but not all. The Volvo
engines I had in the Navigator supposedly would self prime and purge but I
never tried, other than restarting after a fuel filter change.

Others can be a bear to purge and get running again. Best bet is just don't
run them out of fuel.
