Ford 6.7 PSD recall due to CP4 pump and COVID19

I was reading that Ford has determined that certain year Ford PSD trucks due to the CP4 pump failing and it was blamed on diesel sitting in tanks during COVID19 and people filling up were not getting fresh fuel. I can understand that although with the two filters in those PSD trucks should have filtered out water or bacteria that had grown.

What I cannot understand is why they are not recalling all PSD pickups with a CP4 pump. I think the recall was 2020 to 2022.

They should just recall all the 6.7 PSD and put in a different pump. The CP4 is a great pump until you get a bad load of fuel or the pump wears. Then it's a $10K to $12K repair.
 
I think its important to note that the blame was on biodiesel, which is a convenient excuse along with a covid excuse. You are posting your interpretation but the full text would be helpful. Here it is:

"Ford is recalling nearly 300,000 Super Duty and Medium trucks due to complications stemming from—and we really can’t make this up—the COVID-19 pandemic. The impacted trucks shipped with 6.7-liter diesel engines equipped with a high-pressure fuel pump (HPFP) that is sensitive to the buildup of deposits found in biodiesel that has sat too long, like during the long supply-chain disruptions that resulted from the outbreak of COVID. Over time, these deposits accelerate wear on the pump, leading to eventual failure.


The recall applies to the 2020-2022 Ford F-Series Super Duty and Medium Truck lineup (F250, F350, F450, F550, F600) equipped with the 6.7L Power Stroke.


The recall report is rather matter-of-fact about the nature of the failure. After all, it’s a fairly mundane issue. Ford says the deposits will form on the pump drivetrain roller and inside the tappet body cooling passages, where they’ll increase wear on the pump components and introduce debris into the fuel system. Partial pump failure may result in long cranks, poor power delivery, and a “check engine” light. Once the HPFP fails entirely, you’re stranded.

It took Ford a while to track this one down. The company first noted an uptick in warranty work on the high-pressure fuel pumps in trucks equipped with the 6.7-liter “Scorpion” engine in September of 2021. Initially, Ford suspected a bad batch of fuel pumps—the infamous Bosch CP4 HPFP, no less. After replacing the part with a newer, more robust unit in production, Ford (in communication with NHTSA) observed that many of the initial part failures could be traced to a single cause:


“Between February 2022 and October 2022, Ford continued to evaluate warranty data trends, review returned parts from the field, interview customers and analyze connected vehicle data,” Ford’s chronology said. “Based on this analysis, Ford determined that the failed pumps were a result of aged biodiesel caused by fuel sitting for extended periods of time during COVID shutdowns.”


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."
 
Nothing is loaded in OASIS yet as far as the parts requirements or repair procedure. When searching for the 24S78 it says "There were no publications matching your specified criteria." so its probably too new. Disclaimer this is as of the posting date and can change.

I thought that I'd heard too that it was a bad fuel supply (older fuel), during that time period, that may have contributed to the issue. Either way I'm sure many folks were not using a fuel stabilizer so not helping matters. Keep em hot or stabilize. :)

I was thinking it was fuel in the gas station tanks. Not in the tanks of people's trucks. But I could be wrong.

I know it's diesel fuel. But people still call them gas stations.

So why only certain years with a CP4 pump?

So what about prior year trucks with a CP4? The cooling was not an issue?

Why is Ford accepting any responsibility if it's fuel related?

Is the 6.7 Scorpion a high performance variation?
