The Cummins engines are designed to have the fuel filters installed dry. Once the filter is installed, you cycle the ignition switch on for a few seconds while you here the fuel pump run. You do this several times. With that said, I've found that this often doesn't work. (Someone will come along and say it works great, but that doesn't help when you can't restart your coach and start to panic.)It never worked for me!!
I like to prefill my filters. Fuel enters the filter from the outer edges and exits via the large hole in the center. You always fill the filter from the outer edges so the fuel you introduce during the filter change is filtered. Many use a pvc threaded plug to plug the center hole. I just clean my hands and insert my fat thumb while adding diesel fuel.I use a short pipe nipple"screwed" into the center hole
Reinstall the filter, making sure you reinstall the new O-ring(s) that came with the filter and reconnect the electrical connection. No need to get a gorilla to install the filter or use a strap wrench. I tighten mine with my hands until snug.
Move to the next filter. Same procedure. Once done, fire it up and check for leaks.
Here is a procedure I just posted yesterday for changing the filters on my new Dutch Star.
