Considering fuel pump problem when buying Cummins

[imalumberjack]

My experience ..... I have a cm2250 isx 12 that I bought with a failed pump. Cummins quick serve shows only a replacement pump, no barrel and plungers and no tappets no head not even a head gasket the only part available on quick serve is the shear pin and maybe the gear. I purchased the parts from bigrig.com, just bought what I seen as fitting a cm2250.
