air in the fuel line!!! how do i get it out???

I did a filter service on my 2002 transit, 2.4l turbo diesel engine,
I changed the fuel filter, and when i replaced it i didnt prime the new one, I thought the fuel pump would do it for me... NOW, i got the engine to start and it ran fine untill the fuel in the lines ran out, then in started once again after that, i turned the engine off (i probly should have let it run)and now it wont start.
I've checked the level of fuel in the new filter. its in there.
