I'm looking for a pic of the passenger side of a 88 13b na that is running right to see if I'm missing a vacuum line just under the air inlet tube. There is something mounted to the block right behind a vacuum line off the air inlet tube between the injectors with a metal tube that looks like it should have a hose runnin off of it.
Any help would be appreciated I'm not sure if it is suppose to have hose if that could be the item causing my problem so I would like to see if there is a hose where it is suppose to run to.
If you would be kind enough to email a pic to jbursen@sbcglobal.net it would be helpful.

 

It would be easier if you post a picture of what you think is set up wrong. There are unused vacuum ports, and this may be one. I can't tell what you mean from the description.

 

That metal yube goes to the 5-6 port actuators. The line would then go to a fitting on the tube that goes from the air pump to the cat. They require pressure, not vacumme to actuate the valves. Hope I helped.

 

Thank you for the info it helped
