They look almost like float bowl vents or something, they're just like small nozzles that stick up out the top of the carb. I don't know what they're for, but she runs great without them hooked up to anything! I just got them on the car and it runs AWESOME compared to the SU's. The Dellorto's idle and rev beautifully! It's definitely got more power all the way through the entire rpm range. I don't know why people think the SU's are better for low end torque/streetability the Dellorto's are WAY better just from a seat of the pants view. Now I don't know what to expect for gas mileage, but it can't be too bad, we'll see. Thanks for looking up in the books for me, I'll let you know how it runs at the strip. I can already tell I'm going to have a way better time. See ya later!!
