I’ve been running the truck pretty hard the past few months, with trips to Georgia, Washington state and southern Indiana. I thought I’d get some maintenance done.
Oil change and filter, no problem
Air filter, again no problem, although it looked terrible. I’m surprised the truck wasn’t showing a restriction.
Fuel filters. I must have done something wrong. I grabbed a 5 gallon bucket, slid it under the truck, then opened the water separator valve. I let that drain while I changed the filter on the engine. Upper filter change went well.
As I slid back under the truck I noticed my bucket now had about $20 worth of diesel fuel in it. I was expecting about 2 quarts max, not 5 gallons. What was my error here?
Uh oh, that's the same method I use, drain lower while replacing top filter. I thought maybe doing it that way helped avoid the siphoning issue that some experience.....I guess not. I haven't had to try any other way yet, but some advice and techniques I've read that work are to have 1/4 tank or less, or open the lower filter housing before too much drains out.

Did it stop, or did you decide to close the valve and do it another time?
Opening the bottom filter housing is supposed to work no matter what, it does increase the mess.
I had at least a half tank last fuel filter change, it stopped at around a half gallon, maybe less. I am worried that one of these times I too will have to deal with the siphoning.

I stopped it. My bucket was about an inch away from overflowing.
when I do my lower one, I open the yellow valve and then start loosening the bolts. Once you get the bolts loosened enough to open it up it will break the suction and quit draining.
I just did my fuel filters last week with about a half tank of fuel. Opened the drain valve, took a sample right away, then let it drain into a 5 gallon bucket until it stopped. Maybe a quart/quart and a half of fuel and it stopped. Loosened the bolts and dropped the filter cover and filter element. Replaced element and gasket and bolted it back up, then primed the system about 10 times. Then moved up to the upper filter and replaced it. Primed the system again with 10 cycles to make sure it was primed completely. This was the first filter change for my 2022 (16,500 miles). This is how Arod does it so I figured I'd do it the same. Only thing I changed was doing one filter at a time compared to my previous 2019 6.7 and I removed and replaced both filters before priming the system.

Yeah, this seems to be something that happens on some of the pre-2020 trucks, never had any similar issue with my 22.
Open drain, drain into a small jug, never drains more than about a quart or so when it quits.

Might be a challenge to find them, but there have been posts from 2020+ owners who experienced the same thing.

I do the lower then the upper.
I'm impatient, so this is the method I use also. I don't wait for it to stop draining so I've never experienced the siphon issue.
What do they define as "early build" and what is the context of that screen shot? My 2019 owners manual specifies 2017 as the only year requiring removal of a fuel line at the in tank fuel pump as a first step to a fuel filter service.
Did my 19 over the weekend, only got what the volume of that housing holds. What I didn't do and maybe the issue here is the top filter. I did that one first, then did the lower one. I didn't do them at the same time, so maybe by removing the top filter while the drain was opened, caused a back flow problem.
