2020 F350 CP4 Disaster!!
It might be gouging but when they got you by the short and curly....well then, don't pay the bill and see how it turns out while they have your truck.
Any good diesel pickup shop can do the DCR fuel system kit for less than 10K and you get the better pump in the process.
I have a 2020 F350 King Ranch A few days ago the CP4 Pump failed I took the truck to our local dealer to find out Ford isn't support or honoring their own recall. I have been on the phone with Ford all day, to basically be told go suck wind we don't care. The dealer has been trying to help, so no issue with them but Ford is far from ever getting me to buy another truck. They recognize the issue but have placed their recall on hold.The dealer submitted a sssc claim Ford said do not repair the truck! My truck sits in limbo until they figure out what they need to do. This is really a poor position Ford has taken. NO concern for the customer who has spent 100k on a truck! To say the least I am moving to Dodge after this. Ford you lost a great customer! For those who may not understand the issue these pumps leave metal shavings in the fuel system. The repair involves replacing the pump, injectors and fuel lines from the tank according to the dealer.
In your case, the fuel pump itself finally failed and trashed the fuel system - and you are out of warranty. How exactly is Ford at fault for your problem? You stated your truck has 270,000 miles on it. I can't believe anyone would reasonably expect a manufacturer to warranty a repair for something that is 170,000 miles past its warranty period.
And good luck with Dodge. Ask folks on the RAM forums how those new hydraulic lifter Cummins engines are doing. No manufacturer is immune to problems.

this is why I installed an s&s dpk as soon as I got home with my new truck.
The CP4 recall isn't a recall for the pump. It is a recall to change programming on the PCM that is supposed to affect the pump. Question - the recall was issued in January of 2025. Did you have the recall performed?
In your case, the fuel pump itself finally failed and trashed the fuel system - and you are out of warranty. How exactly is Ford at fault for your problem? You stated your truck has 275,000 miles on it. I can't believe anyone would reasonably expect a manufacturer to warranty a repair for something that is 175,000 miles past its warranty period.

And yeah, 270k miles... that's way out of warranty and I would expect any repair to be on the owner at this point. If it's at the dealership, go get it and take it to a diesel shop and get a DCR. Ford isn't touching that without payment.

270,000 miles?!?!? And you think ford should cover this repair at 270k on the clock.
I'm with ford on this one. Its not like its close to end if warranty. It's a worn out truck. Time for a new purchase

I think we are entering the age and mileage slot on these older trucks where these CP4's will be failing more often. My '17 is nine years old and 90k miles, so last week I installed a DCR, $2500 plus my labor and time, but I feel a whole lot better now that its done.
I don't know where you guys are getting that the OP has 270K miles on and is looking for warranty repair.
He has ONLY been talking about the recall and ford pausing that.
Recall is for a safety issue, has ZERO to do with warranty.
Now, maybe some of you guys are confusing the OP's truck with mine, that has 274,000 miles on it.
Mine had the CP4 replaced at 115,000 miles under an extended diesel care warranty.
So, get the facts straight!

If this ever happens to you, tell them you want to talk to the OEM field rep. If the field rep still doesn't cover it and has not provided proof of their assumption that it was caused by an aftermarket part, you just get a lawyer. If the price of the repair does not exceed small claims court limits, you take them to small claims court. Why? Because once you take them to court (small claims or otherwise), they actually have to prove it. NOT just say it, but show actual proof.
Now here is the dirty secret that OEMs don't want you to know; it's almost impossible to prove in most cases. I was a field rep calling on dealers for nearly 6 of my 10 years at Ford. I never denied warranty for aftermarket parts. Not once. Why, because it usually isn't the problem and if it is, it costs most to prove it in court than to just pay the damn bill. In my experience it would be almost impossible to prove adding a secondary filtering system caused a problem with your existing fuel system.
yeah, yeah, I know, everybody has a story of being denied warranty. In about 99.99% of those cases, you are only hearing what the person denied warranty wants you to hear.
I'm glad that when we all breakdown pulling a load it's in front of that good diesel shop.
What recall? Ford has replaced failed cp4’s while under warranty, but I’ve never heard of ford issuing a recall on the cp4.

Recall 24S78 has nothing to do with repairing a failed cp4, it’s a programming change. Ford has been steadfast in it’s opinion the pump is fine and biodiesel deposits or other contaminants is the problem. I’m surprised it hasn’t ended up in court, but I’m afraid until it does if you are out of warranty you are out of luck, and why so many have installed DPK’s, DCR’s, and use lubricity additives.
I use an additive, I also improved fuel filtration/water removal to get me through the warranty, but a DCR is in my future the second the extended warranty is up.
