Hopefully this will include the VM3.0 in the future. Although the Mounting is entirely different. The CP4 on Cummins has the GP the VM3.0 does NOT, that's the only difference

CP4 has always been an issue ( a bit overblown sometimes)... the Duramax LML guys migrate to a Cp3 using a conversion kit a lot to avoid the failure and bombing the entire fuel system.

We all need to keep contacting Stellantis about the fuel pump issue in the ecodiesel. Hopefully they will add it to the recall for the heavy duty trucks. Mine cost me $12k
