Qjet Connection Help
I'm replacing a Holley 4175 with a Qjet and have questions about the connections on the Qjet. There are no similar connections on the Holley.
I've circled the ones I don't know what connects to them, front and rear of the Qjet. Do I just cap / plug these? Thanks in advance for any replies.

Well that’s not a Pontiac carb first off, but that being said, that big front Top 3/8” nipple is for the fuel bowl vent to the charcoal tank which you do not have I will assume.
The other two smaller ones I forget if they are full manifold vacuum or ported. If no one else can give you a answer for those two then just cap then, start the motor a check when they work . I think I recall that on that type of Q jet the rear one on top goes to either the air cleaner or it auto trans vacuum. Sorry, that’s all the help I can offer!

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
