I just had another idea. I think one can carefully bore a 1.25 inch hole
about three inches deep in the exhaust side of the pump. Press and epoxy
in a six inch long sleeve that mates up with the outlet from the block.

This

will block off the internal  bypass channel in one fell swoop. This should
leave about an 1/8 material on both sides of the tube. The top of the stock
pump will be sawed off.
