The carb that is on the car has a red vacuum plug sealing up the vent. The new carb has a black hose attached from Holley. My question is, what does that hose go to? I see nothing on the car that it could plug into...... Karma has no menu. You get served what you deserve.

If it's a N95 it goes to a 3 nipple breather If it's NOT a N95 it goes to a 2 nipple breather There are no CA 340 SIXPACK carbs

The hose from the large outlet on the breather is connected to a tube on the air cleaner base. This is my car with a single nipple breather and a picture I saved of a member's N95 car.

Agreed, vents to atmosphere, but never liked that on any of my sixpack cars, I always capped the bowl vent tube, no need to have a possible fuel leak/fire that could have been avoided...

Will check the code..... N94 is the Trans Am package. No N95 present, so you need a single nipple breather connected to the air cleaner base & leave the vent open to be factory correct.

This car is soooo nice that I am going to also plug the bowl vent with a black, fuel capable plug and not that red vacuum plug. I am also very nervous about just letting it vent to atmosphere. I will just be sure to show the owner what I did and why. I am replacing the center carb for one with the correct numbers. The one that was on the car was for a 4 speed car. Also, whoever installed these carbs was a hack. He had screwed up the flare nut on the rear line right at the carb inlet so bad that I had to make a replacement line. It looked like he installed it with a pipe wrench. :0 Karma has no menu. You get served what you deserve.
