CM2250/CM2350 Fuel Pump

[Mrp121]

Just wondering if you can directly swap, take out cm2250 and install cm2350 fuel pump?

cummins has TSBs with the proper parts to swap out the three cylinder pump to the updated 2 cylinder pump about $4000 in parts tho.. I do wonder if the X-15 pump is backwards compatible tho could perhaps be a better option if the geartrain housing will accommodate it.

they are not, and 2250 parts will not fit in a 2350 and vice versa. x15 pumps are configured slightly different aswell with individual high pressure lines and individual barrel/plunger assembly on the pump heads.
