In the continuing saga of my pool pump, I've now replaced the pump motor, impeller, shaft seal plus o-rings and seal housing, and water is still gushing out. Inspecting it more closely, it seems the water is coming out from outside of the seal housing (see video linked below). I've doublechecked all the o-rings and gaskets and lubed them with Magic Lube. I feel like I must be missing something obvious.
Here are pictures of re-assembling the motor, maybe that will help provide a clue. Any help is much appreciated!
