Can you confirm whether injector part number 4964170 for CumminsQSK19CM850 engine has been changed to a new part # 4955524 | Cummins QSK19 - Tier 3 Fuel Injector (New)
I have injector part number 4964170 for a Cummins QSK19 CM850 engine. However, another supplier told me that this part number has been updated to 4955524.
Could you please confirm whether the Bosch injector (part number 4955524) listed on your website is the correct replacement for Cummins part number 4964170 and is compatible with a Cummins QSK19 CM850 engine?
