My lift pump broke right at the mounting flange on the engine side, it was the little support for the rod that broke actually... Where is the cheapest place to get a new one.. Or can a guy buy a electric pump to replace it ?

The lift pump is readily available from Cummins, for about the best price you can find. You can also obtain a FASS electric system to replace the pump, but the replacement mechanical pump is much less expensive.

I am a bit confused by your description of what broke. There are two bolts that hold the lift pump to the block, the water separator and fuel heater is on a flange mounted behind it, and the pushrod goes through the hole in the pump and though the block and actuates the lift pump from a cam lobe. From your description, I take it the pump housing itself broke where the pushrod enters the housing. If so, that will be part of the new pump.
