Holley carb leaks gas

Valiant63 said
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.

Normally those o-rings leak quickly if they are installed wrong. Put a dab of vaseline on them then be sure to insert them straight into the transfer tube hole to be sure they don't twist. Since the carb was so recently rebuilt, likely the o-ring was twisted and finally split causing the leak.
