Are the current model turbo diesel fuel systems more or less difficult to bleed if you run them out of fuel, than the old mechanical pumps and injectors. What needs to be done to get going again. I have not done it yet but it is probably likely at some point.

Don't intentially run out, you can stuff your pump if you try to switch tanks after you run out, while still in gear driving the motor down the highway, with no fuel in the pump.If you do run out, then open the bonnet and pump the primer on top of your filter continuously until hard. Then wind the starter (and if possible if you have someone with you) continue pumping the primer plunger and the engine will start. If no one is with you, pump until hard, give a 5 second crank, pump again etc. There may be a better way if you can get the plastic plug out on the pump cover, as there may be a bleeder under it, but I tried on the side of the road and couldn't get it out. However, if you could bleed to the pump in the usual way if there is a bleeder under the cover you will have no troubles. If you have a pair of pliers, take the fuel outlet hose off the filter, and pump until the filter is full and fuel is flowing, then put the hose back on and pump again until hard etc. This will make starting easier. I hope to pull all the covers off soon to get a look at the pump and see if there is a bleeder there somewhere.
 
On the older models up till 98 you remove the glow plugs and undo at least 3 injector lines.
Disconnect the fuel line at the the pump and use the hand primer until you get fuel and reconnect.
Crank the engine until all 3 lines have fuel at the injector end
With no glow plugs there is no compression and the engine spins around really fast.
I dont think is a bleeder on these pumps.
If your going to bleed a diesel you need to carry some spanners and especially a 10mm injector line spanner thats fit onto the trunnions
 
I ran out of diesel in the hill down towards the filling station....
Just rolled in (lucky the single D pump was free), filled up, 2-3 strokes on the primer pump, cranking maybe 10 secs, end of story. Wonderful. :cool:

PS: on my old volvo it took around two hrs....
