I measured the inside dia. of my 20b water pump housing last night... both inlet & outlet i.d. is 1.25"; outside dia. are both 1.5".  Looks like they will need to be welded in order to use them on the 20b.  Mark S.

Won't hurt to butt weld them but the wiggins could be bored out and the barbs either
cut off or ground down on the pump and the wiggins bonded on. Most pumps
are corroded anyway in the area of the pump attachment. A little sanding in that
area to clean them up and I will bet they are considerably less than 1-1/2 inch
in dia. The wiggins are 1.6 inchs OD so a 1-1/2 inch bore would leave an
an 0.05 wall which is plenty.
