I wonder if I could trade a CP4 for a chopper?

I use Archoil diesel fuel additive in my diesel fuel. You really should be using something with a lubricant package if you have a CP4 pump and this fuel additive doesn't harm the diesel exhaust filter, it has been demonstrated to be good for it. You maybe should look into it.
 
Two things the CP4 doesn't like. Lack of lubrication, I always added some type of fuel lubricant every time I filled my truck up, second is debris, that will wipe your pump out real quick, I had an aftermarket MPROP in my CP4 that had a double 20 micron screen and would stop any large debris from entering the pump.

My buddy had his CP4 grenade on his '11 and it cost him 10k.

If you're really worried about it a FASS should be enough to filter anything out that would destroy the pump and if you're extra paranoid you can get the FASS & DCR pump.

As far as deletes go I have owned deleted diesels from 2013-2023 and have driven all over the U.S. towing illegally (too heavy, no CDL) and never had an issue, been pulled over too and the cop never said anything, passed plenty of weigh stations.

Iā€™ve always used Hotshots EDT every fuel up. Iā€™ve been meaning to look into the Archoil because there has been some documentation that it actually prolongs times between regeneration.
 
Problem is itā€™s not really Fords problem (in my belief), The CP4 is on millions and millions and millions of cars in Europe and they donā€™t explode. The USA has stricter guidelines on the ULSD so it actually has even less lubricity in it then ULSD in Europe.

Itā€™s the design that can fail catastrophically and can cost $10,000+ to fix. It the same nonsense that Ford used on certain transmissions that caused early wear that killed the transmissions, only on a larger scale. To save a few pennies they put the customer on the hook for thousands. Iā€™ve had more Fords than any other brand, so Iā€™m not by nature a Ford hater.

P. I. N. T. O.

Oh, and lets not forget the Explorer/Firestone tire fiasco...

Iā€™m also a staunch believer that Americans are lazy. Change your fuel filters every 15k miles and most CP4 explosions likely wonā€™t happen. šŸ¤£

I don't understand how a dirty fuel filter leads to dirty fuel

I can see how a dirty fuel filter would lead to reduced fuel flow and eventually a stoppage

But I don't understand how a filter with a certain micron rating is going to lead to unfiltered fuel getting past that filter unless it is bypassing.

Serious question

Anyone taken one apart?

I do recall a thread a couple decades ago on BITOG, where they compared oil filters, and determined the reason one of the supposed best oil filters, tended to do worse in UOAā€™s. They determined that the filtering was so restrictive, it didnā€™t take long for the filter to open the built-in bypass valve, at which point, it was no longer filtering anything. The bpv was there to avoid potentially starving the engine of oil flow, but it also meant filtering wasnā€™t happening once it opened.

I wonder if the fuel filters have something similar to avoid fuel starvation if the filter gets clogged? Seems like it would be a poor design (Iā€™d rather have an easy-to-access fuel filter, working like a fuse, so if it encounters a lot of dirty fuel, it clogs. Vehicle doesnā€™t run. ā€œHuhā€¦ fuel filter needs to be changed againā€¦ā€, rather than opening a bypass and potentially resulting in $$,$$$ worth of work.
