@rhod3house - Not good! Scary that you are already using the higher frequency 15K mile fuel filter schedule and suffered an injection pump failure.
While researching my response for Post #21 in Surging thread, I was also alarmed at the number of CP4-related class action lawsuits against all three (3) of the US truck manufacturers. Bosch earned a pretty good reputation with their bulletproof CP3 pump, which is probably why all three used the next-generation CP4 pump in all of their diesel platforms. I did enough research to learn that the pump in our F150 Diesels is indeed the Bosch CP4.2 injection pump.
The major problem is that when the pump fails, not only do you need to replace the pump, but you also need to replace pretty much everything else in the fuel delivery system downstream from the pump; e.g injectors, fuel rails, hard lines/pipes, etc. which is what makes this a $10K service job.
While not an F150 PowerStroke Diesel, @Orangeman chimed in very recently regarding a used LandRover Discovery he just purchased needing a new pump at 40K miles: Bosch CP4 Fuel pump issues, need replacement at 40k miles
All of the class action suits blamed the lack of lubricity in ULSD as the cause of the pump failures, and since all three truck manufacturers are using this version of the pump in their engines, I think the writing-is-on-the-wall that we should all expect to see premature injection pump failures due to lack of lubricity = taking no action is like continuing to smoke after being diagnosed with emphysema.
What options are available to us as owners to combat this known prognosis?
This looks to be another joy of diesel ownership...

- Run a Fuel additive specifically to boost Lubricity in your fuel;
e.g. Stanadyne Lubricity Formula - Drain water separator on a frequent/monthly basis
- Switch to more frequent fuel filter service cycle; e.g. no more than 15K miles
- Engage someone like XDP to create a CP4 By-Pass Kit for our F150s;
e.g. XDP 6.7L PowerStroke CP4 ByPass Kit
=> Highly unlikely any vendor will produce bypass kit given small # of F150 PSDs Downgrade to CP3
=> Anyone know if this is even possible on our F150 3.0Ls?
=> Highly unlikely any vendor will produce downgrade kit given small # of F150 PSDsExtended Warranty through duration of ownership
=> Doesn't solve issue but places repair responsibility/cost on Ford
=> See next post for strike-thru reasonStart/Join a class action lawsuit
=> Need enough failures to warrant a class action lawsuit
