So that would be float open and in the case of an electric pump it would be pumping for 30 secs?

Bck, keep in mind the j tubes have windows in them to prevent fuel pullover/siphoning, unfortunately this is where the cracks originate.

I have to take a look a closer look at mine. This is the only pic I have and I don't see any windows.

1, That's why I like Edelbrock. No gaskets below the fuel level and all of them are set up to dump down the throat without J tubes.
2, The race boat uses old style Holley 850's - 4150's. The front bowl's vent would dump outside the carb if over flowed so I did the J tubes on them just to be sure. Even the Holley 600 marine I'm using on my next project had J tubes because both vents on it would have dumped fuel outside the carb.
