Just ordered OEM manifolds. I know the one is a plug and the other elbow is for the water hose. Which is the same as the barr manifolds I am replacing. On the new manifold there is also a drain hole in the middle of the manifold right on the bottom. I would assume one of those other goes into there. One is a reduction sleeve which wont plug. The other blue plastic piece screws into that reduction sleeve or directly into the bottom of the manifold. Can someone please tell me where these go? The diagram for my 1998 5.0gi manifold doesn't show the hole on the bottom of the manifold.
Thanks.
Thanks.
