The reduction in flow I mentioned is becuase when the water is above the primary drain a true siphon isn't achieved becuase air is being drawn in from the secondary pipe. The other kinda crappy thing about this is becuase soo much air is being drawn in the water splashes like crazy in the sump! I've seen the water spalsh up 2-3 feet as air bubble makes its way to the sump!

Not to worry
Once you run 2 separate lines and submerge the main line between 1 and 2 inches below the sump level, all will be good
Only thing that happens is a lot of air gurgling when you first fire it up as the air is purged, splashing water everywhere
I solved this by adding a splash guard around my drain lines

Yeah, currently my return in the sump is submerged about 6" in cylindrical acrylic tubes...yet still continuous 2- 3 foot geysers!

I'm sure you are right that once I run the seperate lines and eliminate the air intake my sump should settle down (after startup of course)
