Holley carb leaks gas

There are small o rings on that tube that seal the tube into the bowls. I haven't "been into" a Holley 4bbl in at least 30 years, but I've been in' a lot of 'em. Has anyone had it apart? Maybe the O ring got displaced or damaged. It's a good idea when you install them, to put a small amount of "anything" on them. Oil, light grease, vaseline
