curiosity question
 

what is this vacumm line for on our tpi cars, maybe tbi as well, dont know, its just on my tpi though. its the one that connects into the tube that connects to the throttle body, it connects right in front of the left intake runner from the set, it pushes into the thing right above the valve cover, throttle body warmer i think. the vacumm line runs back to the firewall and into a wiring bundle and into the car.

The bigger one is filtered air (in your case, measured air) that leads into the passenger valve cover. The other smaller one is for the PCV valve which is on the drivers side valve cover.

i cant upload the picture i want, i took it and modified it with a circle. no thats not it, it doesnt go into any valve covers
