What is Your Correct Pump for KTA38 / KTA50 Engine Model & P/N?
When wanting to match up the correct Cummins replacement pump you do not want to rely on just pump pictures and engine models since Cummins has 3 different pumps for the KTA50 engine models for instance; so you want to always be sure to check what Genuine Cummins pump part number you have to properly find the JMP pump replacement for you.
JMP Marine’s #JPR-C3800 (replaces Cummins 3085649 / 3049157 / 3897669) is the replacement pump for the older style Cummins Series which uses 2 pumps (so 38 Liters). Cummins then developed a new pump for KTA38 and KTA50 Series which replaces the 2 pump setup; one is from Jabsco and the other is from Gilkes.
If your engine has a one pump setup and not 2 then please see below:
