Technical Air in fuel lines!!

[colec331]

What's going on everyone. I'm new to Fiats and more specifically to diesels. I was given a 1993 Fiat Tipo 1.7D non turbo. It's slow but I am trying to do some mainenance on the car. I recently replaced the fuel filter and managed to get air in the lines. How do I get the air out of the lines? This car seems rather simple compared to the mustang I own, but this car is a diesel. Are there any websites to get parts for this car too? Any help would be great! Thanks,
Chris

Loosening the fuel pipes off the injectors works for me and thus bleeds the system.
