DIY FILTER CHANGE

Check this guy out on YouTube. He has all kinds of videos on Pm service on Paccars, Detroits, Cummins, etc. Every kind work, repair, maintenance you can do on a truck, he has a video on it. He used to be a mechanic in the Navy, I believe. He is an o/o. And is now working on getting his own service and repair shop opened up. He does all of his own repairs and maintenance on all of his trucks. Very knowledgeable guy.

My guess would be to pre-fill it about 2/3 to 3/4 full. And replace the o-ring gasket for the plastic bowl. I'm not sure there is one. But I'm pretty sure there is since fluid is going through. Also prime the filter as well. It's probably gonna take about 3/4 of a gallon.

 

On these newer model trucks, I wouldn't put ATF in the fuel filter. Just because of the way ATF is now designed with all of the additives, and the friction modifiers, and such. Now, the older trucks from like the pre-90's models, yeah that was a lot more common. Especially the 2 cycles from way back in the day. They were a pain in the ### to start up again if you ran out of fuel. The ATF in with the fuel filters made it a little easier to start up. In cold weather, these older engines were a pain in the ### to start up. Add in some ATF in the fuel tanks, and the lubrication and a little extra BTU's from the ATF helped start right up. I guess it acted sort of like 2-cycle engine oil. But now we've got these motors that run on high-tech computers, emissions systems, injectors and injection pumps, and everything else. So I would just stick to using clean, filtered diesel for priming fuel filters. Better to be safe than sorry. Especially with how much these emissions systems repairs and maintenance costs are.
