Pump drain plug help

[Tnixa]

I have an older shallow well pump that i winterize every year. Part of the area where the drain plug screws in has rusted off so I attempted to install a needle valve so i wouldn't have to remove it every year. But while screwing in the needle valve it started going sideways so maybe the threads were not the same as the plug. The drain plug would not screw in nicely afterwards but I was finally able to get it to go in a bit but still not as far as i would like.

Should try to use a tap to clean up the threads or is replacing the pump the better option?

Looks like part of the boss for the threads on the pump is broken off? May not be enough left to thread. 1/4 NPT pipe tap will work if there is enough meat left to thread.

Correct, some of the threads are broken off on the left side. There are about 4 or 5 threads left.
