Bypass hose and fitting dilemma

There is a place called FittingsandAdapters.com that has all of those fittings you can't find elsewhere. The one for the Holley intake is part no. BHB-12-12, 3/4 hose id. and 3/4 male pipe thread. I'm sure they have the water pump fitting also. You have to look real hard on their website so you don't overlook them.
