CM2250/CM2350 Fuel Pump

[Jose9640]

Ive been reading up on the infamous fuel pump issue. I have a cm2250 that has 200k on new motor and had the fuel pump updated. I just bought a cm2350 with 600k. what has to be done to correct this issue? I see there is a rebuild kit. is this some type of aftermarket deal or a cummins part?

I bought My rebuild kit from cummins it was very cheap they use to be like 3 or 400 and now if I remember they are like $40 I could be wrong but I know for sure not more than $100- I have the 2350 engine as well in 2014 kw

I am thinking you have some serious mis-calculation in those prices there.

I would never put an after-market part in my engine as a critical component that can cause engine destruction,.. so i would say stay away from any after-market fuel system components for sure.

As far as part#'s and prices go, maybe someone can elaborate with some actual part#'s etc.

Im not really worried about the price. I just want to get it done right. So I need the tappets, barrels, plungers and the seal washer correct?
