Throttle bodies

Ok, got a question for you. I bought a TPI setup from a guy that had it on his Corvette and I noticed that on my original tb I have an extra vacuum port and was wondering what it is..Thanks.

This first one is off of my original TPI out of an 88 IROC. I'm wondering what the middle inlet is.

This is out of the vette. It doesn't have that middle inlet.


Could I just drill it out and tap it and put a nipple in it? Will that work ok?

Re: Throttle bodies

It looks like either the EVAP line, the one that comes from the charcoal canister. Did you check to see that the other side might have an extra line???

Re: Throttle bodies

Yeah, you're right. It is the EVAP line. And no, there is nothing on the other side. Thanks.
