Questions on Kettle Upgrade

I recently purchased a cheap solar pump to circulate my mash and aid in whirlpooling. I plan to attach the pump directly to my kettle's ball valve on one end. My question is about the other end, which will be toward the top of my kettle. I know I need a weldless bulkhead. What else do I need? Anyone done what I intend? Advice? Pics?
