You can have the res below the pump but it makes it difficult to near impossible to keep the pump wet while filling the system. The issue is that you usually fill the system at the res and then the water trickles down to the pump. Then you just keep the res full and turn on the pump and it will start filling the system and air will stay in the res and you just keep filling it.
That will not happen if you mount it like that. You can make a filling tube above the pump with a y or t fitting or if your radiator has extra ports you can fill from there instead.
You can buy a new pump top that would allow a fitting to come straight out the top then you could mount the pump directly to the bottom of the reservoir or if you have a tap you could just drill out the center of the pump top and then tap it for g 1/4 and plug up the original inlet. I'd recommend the aftermarket route though. There are affordable pump tops out there.
Or just mount the micro res somewhere else.
When filling the pump is gravity fed which is why the fill port needs to be above it... Your res is your fill port. Once the system is filled the pump is no longer gravity fed so the res can be anywhere. I hope that makes sense.Edited by givmedew - 8/6/13 at 5:59am
