![]() => Highly unlikely any vendor will produce downgrade kit given small # of F150 PSDs => Anyone know if this is even possible on our F150 3.0Ls? => Highly unlikely any vendor will produce bypass kit given small # of F150 PSDs Engage someone like XDP to create a CP4 By-Pass Kit for our F150s.Switch to more frequent fuel filter service cycle e.g.Drain water separator on a frequent/monthly basis.Run a Fuel additive specifically to boost Lubricity in your fuel.What options are available to us as owners to combat this known prognosis? While not an F150 PowerStroke Diesel, 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 milesĪll 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. which is what makes this a $10K service job. 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. I did enough research to learn that the pump in our F150 Diesels is indeed the Bosch CP4.2 injection pump. 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. 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. Has anyone else had an issue this early with their fuel pump? Ive read that it happens around 100k, but man, mine seems just was too early and thats got me rattled, since this is my work/personal truck.īeen debating about downgrading to cp3 if possible, or upgrade to FASS system down the road if need be.Īny and all info is - Not good! Scary that you are already using the higher frequency 15K mile fuel filter schedule and suffered an injection pump failure. The lucky thing I have on my side is that my truck is still under warranty and it wasn't a battle to get it to be covered. Been digging through the interwebs and found ALOT of info about CP4 failures in dodge, GM, ford 6.7s, and the class action lawsuits that have been following. ![]() Got a call that afternoon saying that they found metal shavings in my fuel system and the truck wasn't going anywhere for a while. So my truck went in for its last maintenance oil change and a check engine light about low fuel pressure. So fuel quality isn't much of an issue as far as I can tell. Before you read, my filter replacements are done at 15k, but will probably ramp up to every 10k, and i get diesel at valero, shell, and HEB.
