OT: cummins fuel filter

hey guys i know this is off topic but i thought i would ask here because you are the ones i trust. my buddy asked me to change the fuel filter in his 2003 dodge 5.9. my question is do i need to purge the lines for air when i change the filter? thanks in advance, jake.

I sure would! They're awfully tough to start if you don't.

Don't they have that little primer pump on the side anymore?
I thought they had a little lever that you operated to prime them.

Or am I thinking old Mercedes????

Aren't they a spin-on filter? if so just fill it with Diesel and spin it on...I used to drive (and service) a Freightliner FL-70 with the Cummins 5.9 and if I remember correctly IT has a spin-on fuel filter, and besides that I ran it out of fuel once and just cranked it until it started........I think it does have the primer/pump arm on it though.

I have helped my son with his Cummins and we would just crack the line at each cylinder to bleed the air out and it would fire right up.

Bigcat has it, when I change them at work I just crack open the first injector nut. Once you see a couple drops of fuel you know the airs out, tighten it up and your ready to go.
