I know....the instructions are horrible hey!?
I took mine apart and now I’m not sure if I have the impellers back to the correct sides.
Do you happen to remember if when you have the pump installed like pic. #2..which way the impeller fins should be sloped? I would’ve though the ‘widest fin angle’ would point/align with its rotational direction - but hoping to confirm.

if you or anyone could help with this question would be most appreciated.
