Alright, so I am doing an EFI Swap into my 1968 coupe. On the underneath of the intake where it curves over the valve covers there are a four items that I do not what to do with. Two of the items are like nipples with one plugged with a rubber plug and the other attached to a rubber hose.

The other 2 items are metal pieces that are screwed into the intake, with one about four inches long with a wire attaching to the fuel regulator.

What are these things? Do I need them for my application in a 1968 Mustang with a 302?

Thanks

For the MAP sensor......I do not beleive a mass-air equipped 5.0 uses them. Probably why one port is capped off. But not really sure. I still use speed density.

Thanks for the reply, that picture is great. I now plan on pretty much capping everything off since it seems I don't really need any of those items. I will still attach to the fuel regulator though even though I am not sure exactly why it needs to be.
 
Hey everyone,

Question that I have regarding this thread. Currently I have all the items described above plugged up. I am not convinced this is right. Resultingly, should I have any of these going somewhere like the breather cap on the passenger side valve cover? How about to the throttle body? What has everyone else done. Thanks

no, the nipple on the breather cap on your valve cover goes to the 90* nipple on the throttle body. here is a pic. notice the black hose going from the throttle body to the valve cover. hook up the upper intake like in the picture above.
