Does Cummins use the same pump as Powerstroke cuz I just read that the Cummins has a 29000 psi fuel delivery system where as Ford claims they went to 36000 psi for 2020? I think both use the Bosch 4.2. How does that work?
Edit: Upon doing further google searches I found evidence of a CP4.2 pump failure in a 2020 Ford. Even if the pump has been changed for 2020 it sounds as though it’s still a POS. It seems almost unbelievable that Ford would stick with Bosch even if the number of failures are rare the damage these failing pumps do to the Powerstrokes reputation has got to be costly to Ford.
