Time to figure out a new layout...
If it was going to work at all... then it would work - period.
If you have tubing going from the res to the pump... unless the pump is physically HIGHER than the RES... there is no way it would not flow to the pump. Can you be a little clearer on how your planned loop is set up?
As long as the reservoir is above the pump and connected with tubing... it will get there (even if it has to go through a couple of 90 degree bends to do so).
The only alternate to filling the res and running short pump cycles to fill everything else would be to have a radiator with an open port on the top (not being used obviously) or a Y-fitting with a fill tube and plug which you could then fill and let everything work it's way down through the return on the res. Note however, that this will only work if your return is located at the bottom of the res and the fill location is the highest point in your loop. If the return to the res is at the top, or close to it, there might not be enough gravity to get everything returned sufficiently without pump-cycling.
It just seems like you're overthinking this... have you looked at some of the simple loops in this thread?Edited by DiGiCiDAL - 5/18/13 at 2:19am
