I had an older style Bosch rotary pump rebuilt which they upgraded to newer specs and it cost me about $650.00 , oh yea that included injectors too for cpl 858.
New VE injection pumps are not available from Cummins, Best bet is to have yours rebuilt. Pump shops can "remanufacture" the pump or fix only what is broken.
They aren't very complicated and the kits are cheap, you might give it a shot yourself. I assume your talking about a VE pump. Inlines are a lot more involved.
