I removed the tube that goes back along the head because I am attaching an air conditioner bracket. Does anyone have a source for a hose fitting for either the water pump 11/16-18 or the reducer on the water pump? I have been looking for hose barb fittings but they don't come in those sizes.
Isn't the outlet on the water pump housing 3/8 NPT? http://www.mcmaster.com/#barbed-hose-fittings/=12dd4ti

Are you then going to run heater hose from the water pump to the heater core?
Right, John.
I believe you'll find that the threads are 3/8th NPT, which are the same pitch as 5/8-18 UNF and roughly the same dia., so confusing the two is quite excusable. Nipples for adaptation from 3/8 NPT to hose are fairly easy to obtain.
