Why? The fuel filter setup on our trucks is a good setup.

What makes it good/better than what OP asked about?

Besides the factory system monitoring itself for filter life? It’s a piece of cake to change them. Very convenient and simple. Even uses the same socket as the oil filter. They’re hidden In plain sight and safe from damage, too. Don’t fix what ain’t broke

I was trying to save the OP money.

Here’s my $.02 which you’ll get for free.

My thinking is that this is a solution in search of a problem. The fuel system is easily the most expensive system in the truck. Don’t jack with it. GM has proved time and time again that they will deny a warranty claim and they won’t lose any sleep over it. Don’t reply back with the magnuson moss warranty act stuff with me, I’m very familiar with it.

Also, you’re 99% wrong. Fuel filter life in the DIC isn’t based on mileage. It measures the pressure/flow differential before and after the filters. If you reset your fuel filter life monitor, but don’t change your filters, you won’t see 100% on the fuel filter life. If you clear and reset your ECM which makes everything go default (temps go to 0°, oil and fuel go to 100%) the fuel filter will still drop back down quickly to reflect the filter flow just as the temp will rise quickly to show actual ambient

Oh, by the way, oil life isn’t measured by only mileage either. (Page 267 in my 2016 owners manual) Ever since the introduction of the LS motor, they’ve been using engine loading, revs, etc to monitor oil life. It said the same thing in the owners manual of my old 5.3L fifteen years ago (I’m assuming you don’t read the owners manual) Ever notice how it doesn’t go from 100-0% on an exact mileage figure? It’s not like a Toyota with a maintenance required light that comes on exactly 5000 miles after it was reset every time.

I said mileage is the main component, not the only component. Not sure why you're trying to argue about it. I simply requested that you provide some reasoning to support your recommendation rather than something along the lines of, "gee that's dumb, why would you do that?"

I don't know how efficient the new cotton filters are on these trucks. I do like the fact that they are easy to change and are cheap enough. I don't pull a bunch with my truck or ask a lot of it, no high-performance stuff. The full-size Duramax's, from the LB7 to the L5P, if you wanted to get a better filter than stock and not go with say a lift pump, you got the CAT fuel filter adapter and CAT filter. The CAT filters are pretty cheap; $25 off of XDP vs going to NAPA or any auto parts store and getting one for like $40 (think I remember paying that for a WIX filter). The only cheaper place to get stock filters is Rock Auto (only recently found this place), which you can stock filters on there for $28 to $35. CAT filters had better flow and filtering than any filter that attached to the stock housing if I remember right. And some people just wanted the CAT filter for looks to I know.

But when our filters are so cheap and easy to access, I don't know that I would put a CAT one on there, even if they did make a conversion kit (I've looked before in the past, I haven't found one yet). I mean, if they were dirt cheap, and I was asking a lot from my truck, then yes I would. But I don't see that happening. I would see a lift pump being made for our trucks before a CAT conversion kit if people start doing a lot of high-performance stuff with the trucks.

The cat filters aren’t junk or anything. Why upgrade though? I’m all about modding as y’all know. But, I can just see it now. Problem with fuel system and dealer points to the cat filter system as the culprit and tells you the warranty doesn’t cover it and to have a nice day. But you’re right, people think it’s cool to have the big fuel filters hanging below the frame rail. Not worth it just for the novelty of running heavy equipment filters on a light duty diesel.

If your truck is modified beyond the point of the capabilities of the factory fueling system then that’s a different story. But, for the rest of us, I stand by my “don’t fix what ain’t broke”

Sorry if y’all think I’m being ugly. I’m not known for keeping my opinions to myself.

Having a larger fuel filter hanging below the frame rails would certainly be a reason not to modify the fuel filter setup.

Even on road, kick a rock up the wrong way at highway speeds and you're calling a tow truck...
