Really did it this time!
I gotta throw this out there.
I have in the past just pushed up on the tab with a fair sized screwdriver just enough so I could move the manual valve to where the tab lined up where it is supposed to be in the valve.
This can be done with the valve body in place, and it makes it WAY easier.
I have also bent the tab back to where it sat back down in the valve nicely again after being bent from not being lined up, but it's got to be done carefully and gently.
