Yeah but the SNAPP filter I have on my truck for the S&S DPK and it's replacement 2.1 gen kit of the new aluminum head with the Donaldson filter are pleated. Any can fuel filter or water separator you buy will be a pleated filter, just like the primary filters in our DFCMs (diesel fuel conditioning modules). I believe Ford went to that bigger panel primary fuel filter was for more water separation and more water capacity in the bottom of the housing compared to our DFCMs.
For the 2017+ primary filters, I think its all about improving the water blocking capability, and I think the water block filter media performs better when the fibers are laid out straight vs having to be routed along a radius.

The waterfall situation. Flat folds are also consistent front to back top to bottom where round is wider on the outside than the inside. More surface area to catch moisture.
I think Ford redesigned it to put the pump in the tank itself and redesigned the water separation portion due to too many issues with the DFCM. They are really easy to break if over torqued, and hang out in the open as well. The 17 and up filter is tucked up out of the way, the larger tanks have them sandwiched between the side rail and tank.
Once Ford went with the big panel filter and housing, then yeah, they had to redesign the primary pump system so it only made sense they put it in the tank but i believe this had more to do with increasing water separation and hence, water holding capacity than it did with the 11 to 16 DFCM hanging out in the open, it does have a plate that protects it, and I'm still on my original pump housing and cap -- no broken stops. But I did order a spare cap, sensor and drain which I still have. When I was making phone calls to shop around for the best price on a Air Dog 4G pump, I heard more than once that the DFCM pump is a good unit. It makes sense to me that Ford wanted to CYA themselves more by having what I described above by what do I know... I'm just a LEO who reads a lot and likes to still do maintenance on my own truck...

Reason: Correct post
When I get a chances, I am going to my local dealer with which I have a pretty good relationship with the parts department. Had a employee sent me up with my own account for part discounts who was a friend of one of my cousins, but it probably helped I showed up in uniform...
Anyway, going to compare the FD4615 upper filter to the FD4625 upper filter and first off, see if they redesigned the upper filter in the 4615 set.
So I changed my fuel filters yesterday and noticed the upper fuel filter for the '11-'16 application has not received any of the additional reinforcements to strengthen the top side of the filter. Perhaps it wasn't necessary with the two ports compared to the three port filters. Filter kit was purchased this weekend, so it should be the latest version for the original Super Duty's. Also I noticed on some of the failed filters, the injection molding of the housing looked grainy and these two look like they have a smooth finish.
BTW, where did you tap in for the addition fuel filter? I am thinking about scrapping the OEM set up and going the 1-14 threaded filter head route now that I am out of warranty.
there are two sets of install instructions for the afe dfs780, both show different feed and return disconnects that can be used to connect a different lift pump filter or filter. You will need to order a set of male and female fuel disconnects, obtain a crimping tool, and some crimp clamps.
if you have a 17 thru 19, the instructions that use the mid frame quick disconnects are easier than the rear bear tank disconnects. That yellow rear quick disconnect is a PIA to disconnect t .

Plus a way bigger filter to boot, plus more water capacity, I'd imagine, in the bottom of that bigger filter housing from the DFCM I use.

Filter on the right is the new filter
I've got older filters sitting still sitting in my garage, still with fuel, going to look at them and see....
Yeah gelling can be a big problem for the CP4, especially on the unpinned buckets on the 2011-19, get that thing turned 90*s and the will be toast in short order.
The OEM fuel system provides three times more fuel than required. My understanding is the bypass cuts down on the amount of fuel being returned to the tank and recirculates previously filtered fuel to the CP4. I could be wrong. I can't imagine Ford pushing 10 micron filter fuel to the CP4 and expecting sufficient wear rates.

parts list for a 17 thru 19
11 thru 16 would be about the same except some quick disconnects by the fuel conditioning module might be 3/8’s instead of 1/2”
total cost for dual manifold with 10 micron water seperator and 4 micron particle seperator would be in the area of 318. Compared to 700 for FASS and 900 for spe for the same thing.
