I am currently looking at upgrading my setup from a single Hydor L35 (nice pump, its moving to my second system) to most probably an MCP600 pump with the option of adding a second in series down the road a bit per Cathars rather nice results of dual 600s @ 13.8 volts.

This is where my confusion sets in....

To add a second pump in 'series' do they need to be adjacent in the cooling loop or would it make more sense to have them separated by a waterblock(s) or heater core?

Which solution if either would work better?

A. Pump1>>Heater Core>>Pump2>>Waterblock(s)
B. Pump1>>Pump2>>Heater Core>>Waterblock(s)

Would there truly be any difference?

The primary reasons for considering running 2 pumps in series are twofold- first I would have a 'backup' in case one pump failed to start. Second (and the lesser of the two reasons) would be the performance increase. I was also planning on adding a 13.8vdc 4amp power supply in order to power these pumps without hitting my primary system power supply.
