ok So trying to get all the kinks knocked out of my New 90 chevy silverado (New to me)but after overlooking everything I came across this..im ASSUMING its some sort of Vacuum line which i would like to get fixed/replaced or looked at asap...

here is a photo of it

its under the air filter next to two other vaccum type lines on i believe that is the throttle body?...soo where does it go to??

 

maybe to the charcoal canister. if nothin else, and truck runs good, put a cap on it for now. what year is truck?

 

its a 90..i was just woundering if that would mess with performance or anything....horriable gas mileage right now found out my o2 sensor is broke off *must of just happened*check engine light has been coming on the last week...so trying to get this in tip top shape.dont think it ever had maintaince before..or at least in a long time

 

where exactly is that piece.. pass side,front?

 

got another member gonna go look at his truck to see if he can help figure it out. hopefully pretty soon. definetely gotta replace the 02 sensor. sounds like she just needs a little tlc.

 

I believe on my 87 and 95 that port is capped.

 

my 95 dont even have that port.....

 

Here are two more Better photo's for Referrence..Started the truck up..it is sucking air...so its a vacuum of some sort..





its underneath the Air cleaner..Furthest one to the right

 

yeah..mine doesnt have that. like they said just cap it off lol

 

i'd say put a cap on it, call it good.
