Holley carb leaks gas

My Holley carburetor was rebuilt in January and it worked OK for a few months but now it’s leaking horribly. Why?? it leaks from the back of the front bowl area where the tube is inserted to provide gas to the rear secondaries. Why does it pour gas out of there now when it didn’t leak there before??

I had a five or six second video showing the gas squirting out of there while the engine is running, but it doesn’t appear that I can load the video onto the site.
