Thomas I didn't recognize the Bosch pump right off, You are correct though I believe. The 4 plunger Bosch pumps are $$$$$$$SUPER EXPENSIVE$$$$$$. Very fine units. I have run the 4 cylinder mechanical version on gas cosworth powered race cars. The pump is like another little engine feeding the main one! 20 years ago, I believe the PUMP alone was $4800.00! The system ran very well, but then it should have for what it cost.

Well,
 
I think Bill wants to use the Siemens system.
This is a Bosch 4-plunger - I think here every injector has its own Pump (plunger)
The newer systems run like a regular EFI - one pressurized rail and the injectors control the fuel...
 
However this guy treats a Diesel injection pump overhaul like it is a oil-change!! :)
 
"And voila, we're done. All we have to do is bolt it into ......" :)))

Just stumbled across this site; Is this the pump for the Siemens injection?
