The Infamous New Bosch CP4.2 Fuel Pump

[fritotec]

I have a 2019 Ram 2500 diesel. It is the version that has RAM letters on the grill not the usual ram logo on the grill. How do I know if I have the CP 4 fuel pump or the CP 3 fuel pump? Is the CP 4 only on the high output diesel?

the motor's are all the same. don't think they make a low output motor.

FYI they have both HO & SO aka high output & standard output engines...

Well, 15 months after I received the first Recall notice I am bring my 3500 into the Dealership on Tuesday to have the fuel pump replaced. I am nearly 100 miles from them so I certainly am looking to have them give me a loaner or rental vehicle to get back home if they are having to keep it overnight. In order to facilitate that, my appt is at 10am, and not 7 am. I will not relish waiting around all day, twiddling my thumbs.
