I hope this is a relatively simple question to answer - in the process of replacing the MAP sensor on my Dodge Dakota a rubber coupling on another small vacuum hose broke. The only problem is I don't know what this part does so I don't know which part to replace. If someone can identify what this port is on the Throttle Body (see attached image) and what hose should connect to it, I would be grateful!

Thanks!

 

Its just a vacuum line with a rubber hose connecting it to the nipple on the throttle body. It should eventually find its way back to the vacuum ports on the side of the intake manifold, but thats unimportant. Just go to an autoparts store and buy a peice of rubber fuel line the same diamater as the old dry rotted rubber hose (the part I labled rubber hose in the picture) thats still attached to the vacuum line and replace it (cut the hose off length-wise and take it with you). I had to replace mine a while ago because it was dry rotted and it broke. It should take about 2 minutes to replace.

while your at it, do what i did and replace all the vacuum lines to save the trouble of having another one break. like 95 said it should only take a couple of minutes

 

Thanks guys - I really appreciate the help!
