I was trying to check my fuel pressure the other day and I found this hose that is sucking air. I don't know if I knocked it loose or if it was like that before. Just wondering if anyone can give me some info on what it is, I have included a pic. Thanks in advance.
It is the black one infront of the cap.

 

that appears to be the line for the a/c. should be a hose to the left of it just hanging if that end is still on the plenum

 

That is the line that goes to the vent ducting in the car. There should be a hard platic line floating somewhere behind the head or distributor that attaches to that fitting. I broke the hard line on my car they other way when I was removing the air tubes at the back of the motor and now all I have is Defroster.

 

I have had the same problem ever since I bought the car, (only the defroster works) Thanks for the info!

 

thanks again guys, I just went out there and found where it plugs in. All the vents work now! :hail:
