alpha gen II drive failed presure test, leak found under impelller assy

[stang32]

i replaced the upper seals in this unit, the yoke as well,(scored) i put it all together with a new impeller kit and pressure tested it, 10lbs, would not hold presure for more than a few minutes before dropping. i 1st sprayed soapy water all over the upper unit with no bubbles, i could hear a sound coming from inside the unit, where the shaft runs. then i split the unit in 2 again. i put my finger over the oil hole on top of the lower unit & pressurized it again, found bubbles forming around the impeller cover, removed that and the lower plate and sprayed it again and bubbles are coming from the shaft seal under the impeller pump.
here is a video of what i found

Replace that plastic seal carrier. You should replace it when ever you replace the pump. It just pushes in.
