Pump question

[BrothersBrewing]

So i ditched the king kooker commercial burner stand idea from cabelas, i pulled the trigger on making one on my own. turned out pretty well especially when your friend i a ninja at TIG welding.

i got a question,

where should i mount the pump, and i heard mounting north/south is better then east/west, ive never brewed with a pump before so im open to suggestions.

People seem to have succes either way. Add a valve for venting air out when you are priming. I think this solves 98% of priming issues.
