    Question 4180C bowl vents

    The two vents that exit the carb bowls and lead to the charcoal canisters. I cannot quite visualize how the vents are connected, internally, to the bowl. Seems to me there would be fuel sloshing out at times. Can someone give me a hand or maybe provide a diagram? I'm digging through the Holley books that I have but haven't latched onto an answer. Thanks.

    Simple horizontal & vertical passages. You would need to really stand the car on it's nose (or on it's back bumper) for fuel to slosh out...

    Thanks.
    After reading and looking thru the books and these two images I got it. For some reason I couldn't quite visualize it. Thanks again.
