Thank you Ford Doctor for your reply. I did know that the kit does not prevent the HPFP from failing, but I did not know that with the kit installed that depending on the type of pump failure that shavings would still be sent into the high pressure fuel system. I thought the kit protected regardless of the type of pump failure. That is good to know and helps with the decision, which is not to install the kit. As far as voiding the warranty, you confirmed my suspicion. My frustration with Ford when my HPFP failed was that they were so eager to find any reason to deny honoring the warranty. Right of the bat they said "we can't honor your warranty because of your auxiliary fuel tank." And I responded "what fuel tank." They said "the silver thing in your bed." I had to tell them it wasn't a fuel tank but a tool box. Seriously. Perhaps you have an answer to another question I have asked Ford and no one has an answer, and that is if they are still using the Bosch CP4.2 in the new 2021 models or if they have come up with a different pump like GM did in the Duramax. I sent a letter to Ford inquiring and received no response. A service rep. that came to our local dealer also didn't have the answer. So maybe you have an answer? Thanks again for your response, I really appreciate it!
