I don't have it on this computer, but I did post a pic of my pump.  Nothing special.  I just lopped off the thermostat area from the first coolant sensor outward and had someone weld over the thermostat bypass then weld on a plate to which I bolt an AN-16 Fitting.  This AN-16 fitting goes to the top of the RAD.  An AN-20 fitting comes out of the bottom of the rad back up to the pump intake.

 
I found the pic you posted with the plugged hole, and you cut a good bit off the the housing.  We'd need to see the inside.  Can you get a pic down the outlet hole?  
 
If you start testing this with an electric motor driving the pump, and want to try it with a normal water pump housing, I have an old one in the attic that I'll send you to try.  I'd want it back eventually, but you can use it as long as you need to. 

In fact, I will make a drawing now.

Nothing really sounded wrong with the rest of the layout, but there are a few more jugs than I care for personally.  The drawing will be good, as would detailed pics showing how everything is connected. 

Hang in there.

Rusty (rain for the rest of the week, now that the plane is flying)
