what goes into the 1" hole on top of the upper intake manifold right behind the fuel meter body

You talking those threaded vertical holes by the throttle body?

no. there is one 1" open hole right on top of the plastic plenum on the upper intake manifold. I recently rebuilt my motor and can't find any hose that would go into it. it is not threaded.

Ok I know the one, I'll have to look.

here is a picture of what i mean

Okay. Thanks so much for your help. I'll see if I can find a picture of it

Rowefast you're a lifesaver. I found the adapter. Again thanks a bunch.

Glad to be of help.
