Fuel filters need replacing

[RollTide1126]

I just received a service message for the fuel filters on my 2016 3500 @ 15K. I wanted to know if anyone can tell me what size hose I'll need to drain the filter under the truck. I've watched some videos and this hose is attached to the bottom of the filter to drain the residual fuel in the filter before removing it. Thanks!

There is likely a hose attached to the front filter. Crawl under the front of the truck around the axle on the drivers side and see if it is there.

I believe the rear is 5/16 in. And the the front is either 3/8 or 7/16? Can anyone verify?

I use a 1" hose and slip it over the outside of the factory hose.

There is no factory hose on the rear. And if I remember correctly, the rear drain nozzle is a bit smaller. So i bought some (IIRC) 3/16 ID-5/16 OD vinyl clear tubing and jammed it inside the stretched out end of the factory tube. (The end that was mounted on the drain cock). See picture. The small end fits the rear drain cock, the large end fits the front drain cock. Works flawlessly and not too messy unless i get careless.

Just went out to verify I use 3/8 ID clear vinyl for the rear ,and 5/8 ID piece of garden hose for the front. I keep the 3/8 inside of the 5/8 when not in use to keep together.

Both fit on the outside of the fittings.

I guess 1" would work, I assume you mean 1" ID. I would imagine it would stay on that from hose if pushed up there a bit.

I use 5/8 ID , it slips over the vinyl hose on the front filter hose, I push it on as far as it will go, its just loose enough to get over it easily. Works great, and it was something I had in my garage.

The clear hose the fits offer the rear filter barb will slide inside the existing engine mounted hose that hangs off the drain valve. SNOKING

I used an empty water bottle at the factory drain hose to catch the fuel. I believe it will sit on the front axle tube/differential. The engine mounted fuel filter canister on the '16 seems to hold more than the one on my '02 and '03 did as it overflowed. Never happened on the last ones, will know the next time around.

Just a little tip that I learned the hard way... don't change it the first time over asphalt. If you spill (which I did with BOTH filters) the diesel eats through asphalt...

Yup. Asphalt is the bottom of crude oil at the fractional distilery. Diesel and asphalt are hydrocarbons. Thus, diesel will do a pretty good job of softening and disolving asphalt.

Just do it like the dealerships do. Let it drain all over your truck (just kidding), and then charge you whatever ridiculous price there getting these days. When I was a Cummins Tech at a dealership our service managers policy was to return the truck back to the customer cleaner than when it came in. I don't see that happening anymore.
I never did,buy any special hose (probably should some day). The front filter has a hose on it, but it will soak the front diff before it gets to any kind of catch vessel. The rear filter is easier to access, and,I just use a piece of an old hosepipe, and direct the fuel to some kind of jug or whatnot. Just clear an area under your truck where the fueloil will probably dribble on, and place some rags around that area in case of a spill. Always have a rag in your hand ready to direct the flow of fuel in the general direction it will take. I would advise you,to also wear eye protection. Don't ask me how I know this. Your next question will be; how do I reset the fuel,filter monitor readout. The manual explains,how to do this I think. Someone posted how to do this correctly. I just pushed some buttons (the right way I guess), and it reset.
Changing the filters yourself will,probably save you at least a C Note.

Thanks for the info, I'm off to the hardware store.
