Default 84 351HO Carb gas leak

Hello. I am original owner of 84 supercab with a 351 engine and factory Holly 4V carburetor. Truck runs fine, a little cold-natured like all carbureted fords of this era. Wife said the other day she could smell gas coming from under the hood when driving it. I checked it out and found that when it's running, a steady small stream of gas continuously drips out the front at the bottom - see yellow circle in attached image. I don't wrench much any more so was wondering what the leak is and what can I expect to pay to have it repaired.
Thanks, Mike

Since I got no response and had nothing better to do, I pulled the carburetor off, and removed the 4 screws holding the accelerator pump cover since that looks like where the gas was leaking from. Took the diaphragm out and took it to autozone and they had to order me one, supposed to be here Tuesday. I hope that's all it is.

From the pic and description I would say you are on the right track, just make sure you torque the screws evenly.

Replaced the diaphragm today and that fixed the leak. Thank you
