Air Dog on 04 Cummins

So this is the first diesel I've owned, and I just want to make sure I do things right.

My 04 Cummins has an Air Dog system on it and I need to replace the fuel filter and water separator. I've did a few quick searches on here and couldn't find anything and I only found one video on youtube, so if someone can chime in and tell me the correct way to replace the fuel filter and water separator, I'd appreciate it.

A few questions I have are do I need to clamp off the fuel lines? Do I prefill the fuel filter? If not, do I "bump the starter" or just turn the ignition to run to allow the pump to fill the filter? Any advice and tips would be appreciated. Thanks!
