Very interesting

Ford Just Recalled Nearly 300,000 Super Duty Diesels Because of COVID

Ford suspected a bad batch of high-pressure fuel pumps was to blame at first, until it discovered why those pumps failed.

So 23/24/25 models already have this computer update? If so, then why didn’t the update happen sooner for the 20-22 models?

The issue was said to have been the biodiesel sitting in the tanks/pumps of COVID production trucks that sat on storage lots before being moved/sold. So that's not really an issue with 2023+ trucks.

Something to note : This tells me lots about biodiesel and letting a truck sit for any extended amount of time.

What is considered an extended period of time?

That is the question now. Given the past could we say 1-2 months possibly?? I'm sure we can come together to say what the delivery impacts were from production line lot to the dealer lot hence delivery to the owners. That's going to be part of the whole biodiesel arguments as well.

I'd tell you but it's gross and worse than pumpin' that diesel . Moderators may have to merge this thread with the other one:

From the @Optimus article link :

As for the owners of the 295,449 trucks already in circulation, Ford has not only updated the part but reprogrammed its trucks to improve cooling of the HPFP, which will reduce the buildup of aged biodiesel deposits. Customers with the old parts will receive the same updates and anybody who has already had their fuel pump serviced or replaced due to this problem will be eligible for compensation from Ford.

Not sure if this is a "improper fuel" issue (higher than B20 biodiesel) OR a MUCH BIGGER PROBLEM.....the CP4 isn't really able to handle any biodiesel fuels. Wow.....

I would say yes, and you would likely have the RP8 version CP4.

From my link above :
On August 23, 2021, the RP7 pump was replaced in production with the RP8 variant,which implemented a design robustness action that increased the pump´s roller shoe and tappet body clearances for improved fuel flow to increase cooling in the tappet area.

I'd suggest this parts improvement along with additional data collection (hence fine tuning the PCM files) lead Ford to move to a full on PCM update. So in the parts network the CP4 is the RP8 variant. Hence the need to change the PCM tuning is the first step since trucks are using the RP8, second step would be to replace the RP7 with the RP8 along with PCM tuning.

I (with my perfect timing) ordered a new 21 super duty in February 21. Little did I know that it would be produced and sentenced to purgatory for four months at the speedway parking lot. The biggest issue I had was that the windshield was cloudy. I am not sure why. This was a gasser, so I did not have issues with old fuel.
As for Ford's programming fix mentioned in this thread, I have to agree that they are selling snake oil.

If that’s true mine never sat.

Wonder if this will help folks that have CP4 failures, kind of admitting there’s an issue.

Articles seems to say Ford is going to compensate owners who have already had repairs done. Now...how wide ranging that becomes is to be seen. Is Ford going to give out a blanket coverage or will they reimburse on a case-by-case basis (hence they will review the initial work and possible fuel sample reports from the techs).

 

[Lucky13]

But if a guy replaced cp4 with dcr and filters his warranty will be null and void correct?

 

[DDD]

Great question. This is one of those “duh”moments from the Simpsons or something isn’t it? Let’s just hope we all get the “fix” (whatever that is) before the CP4 meltdown occurs.

Would you agree that 95% or more of CP4 failures are owner/driver error? (Def introduction, water, rust etc)

 

[mrmag00]

So with 36k plus on the truck do they guaranty that the damage it’s already done. Just sounds like they opened a big can of worms admitting there’s a fuel system issue.

Yes, to keep the discussion simple. I wouldn't say water/rust but say those effects are a result of poor fuel storage device being used (hence using a slip tank/in-bed tank).

My money says they will "replace" the HPFP with the RP8 version including any PCM programming. If you already have the RP8 version, they are going to do the PCM programming only.

My suggestive thoughts on the breakdown going forward :
>Any 2020-2022 truck exhibiting HPFP issues will get the full work.
>Any 2020-August 2021 truck with the RP7 pump will get the full work.
>Any August 2021-2022 truck with the RP8 with no issues will get just the PCM programming.
>Any 2020-2022 owner having already paid for the HPFP work is going to need to file a claim for reimbursement of costs. This group might still need the PCM programming.

I don't want these incompetent clowns under my hood!

I’m wondering too. Maybe makes spending the money on a DPK a little less necessary?
