Good evening,

Well here's the problem. Its a 3671918Z 73 340 nipple. I have bought a set from mancini's same problem. Bought yet another from classic industries, too big...can't find that sweet spot. O.D is .631 and another measurement using thread pitch is .591. Can any help finish my intake?

I searched and this is all I come up with not my information. “1/2" npt on the water pump, 3/8 npt on the heater hose”.

If I was you, I would run your manifold down to Ace Hardware down 5600 W. in Roy. Take it inside and check the thread size with one of their examples.

Do you still have the old one? Maybe someone drilled and tapped it out to 3/4"
