I was hoping for some help here. I installed a new unloader and for some reason I am having issues with the fitting leaking at the pump outlet. I tried a brass nipple, a galvanized nipple and now a hex nipple made for hydraulic fittings and they all leak at the point where the nipple goes in to the pump. When I try tightening them down more they break off, even the hydraulic fitting. Should I be using something else?
Thanks for your help!
