FX-1 Where do I tap the stock pump for dual cooling?

[Fx1]

There doesn't seem to be enough meat on the vein part of the pump to drill and tap threads for a 90 degree fitting. Just wondering if anyone else has tapped the stock pump and where?

my guess is you wont find many who have tapped a stock pump. mainly because whatever you have going on in the engine bay that needs dual cooling, the pump is too small for it anyway (if that makes sense). adding a b pipe alones get pretty close to the limits of the stock fx pump. you will probably need to do a pump swap and then run dual cooling if you need to.
