According to Ford, any rtapped air should work out of the system after the engine restarts (although it may be difficult to start). As a result, Ford does not provide any kind of bleeding procedure for this fuel system.

When changing a fuel filter for maintenance, it is usually helpful to refill the new filter with clean diesel before installing it.

Here is a direct quote from the service manual:


Do not run your diesel out of fuel as this will allow air to enter the fuel system which will make restarting difficult. Longer engine cranking time may be required once air is in the fuel system.
If air enters the fuel system (either through running the fuel tank(s) empty or during fuel filter change), the engine may run roughly and produce white smoke while the air is in the fuel system; this is normal and should stop after a short time.


So, the procedure is to crank the engine untill it starts, and tehn allow it to run untill the roughness is gone.
