Vent hole between stuffing box ID and back of impeller
Vent hole between stuffing box ID and back of impeller
(OP)
I am trying to find out if anyone has had luck with drilling a 45 degree hole in the top of the stuffing box that comes out at the back of the impeller on a horizontal barrel pump? If someone knows of this and has a procedure for it I would appreciate the information.

I would try the same approach, make yourself a jig with that hole used as a pilot, then securely assemble it so that it would match the desired location of the drill.
