How to change fuel filter?

Can anyone tell me how to change the fuel filter on my Cummins ISC 8.3 engine. Difficulty, etc. Looks like it would be fairly easy.

    You are actually suppose to fill the filters from the tiny outside holes around the outer edge, but I have yet figured out how to do that well. But I'm told by the big boys that you go to the hardware store and get a bolt that will screw into the threads of the filter, and then with the bolt in place, you hold the bolt with the filter hanging underneath it and slowly fill the filter thru the outside holes. Do I do it that way? I'm not admitting to noth'ng.

    I never have and never will.Just fill the filter.Done at least 10 this way and nary a problem.to each their own

    I have changed hundreds of filters without a problem..First take new filter and prime filter by filling it with fuel from a clean gallon jug.. Put a thin coating of grease on the gasket.. Remove old filter however you prefer, I use a large pair of channel locks... Some fuel will drip so use a catch pan.. Install new filter by tightening it as tight as you can with your bare hands.. Do not use a tool to tighten.. Start it up and drive away...


    I agree as this is how I do mine and nary a problum.Just make sure U prefill the filter fully.or as in my case both filters pri and sec
