What is this?!?!?! came off intake manifold

ok this is for Bigruff.. he wants to know what this is..
came off a toyota intake manifold but his truck doesnt have one.. or something liek that.. i donno

yes it came of an 89-95 intake manifold. 4 cyl fuel injection. but i dont have one on my stock one. that is 91 4cyl fuel injection. so need to know if anyone knows what is for. thanks

looks to be some form of vacuum connection, probably emissions based. if the truck you pulled it off of was from Cali, and yours isn't...thats why you don't have one. Cali trucks came with a bunch of extra crap from what I understand.

lol.. Bigs truck is from cali... He lived there... so why doesnt his have one then? lol that takes that thought out the window

No need to laugh at someone trying to help, you asked for an opinion and you got one. I had no idea he was from Cali, he says he lives in AZ now. I'd still put money on some form of vacuum emissions routing whether or not you choose to keep that thought around.

Was it threaded into the intake or just bolted to it? i know the carb motors have a recirculation system that threads into the intake that you have to remove when doing the weber/holley conversion.

its for the ac check this link they explain it more
