1974 C10 Quadrajet, What Are These Vents?

Hello everyone.

I got my 1974 c10 to run and drive for the first time in 10 years.
It runs pretty good. The only problem now is that when you pump the throttle, fuel comes out of this vent on top of the carb. Ive only tried this with the engine off. This only happens when you pump the gas. I think the fuel from the accelerator pump is leaking through a gasket. It did flood out the carb and make it hard to start later that day. My question is where does this vent go?
I don't believe the quadrajet on my 1972 has these two vents. Once I get the new exhaust installed, I am hoping to drive it 15+miles to the carb shop, if this fuel leak isn't too serious.

Thank you.
