Hello This is my first post but anyways I’m having trouble finding the part number for the nipple behind the water pump that shoots straight out into the valley of the block could anyone help me out? It’s non pi thank you.

 

A picture would help. If this nipple is pressed into the intake manifold, I would seriously consider replacing the intake manifold with the improved version. Back in the late 90's, the original manifold had design defects which resulted in leaks.Your dealer would be your best source for a part number if this part is not part of the intake manifold.
