Luddite, I've read various sources that seem to agree that anything more than 3 psi of fuel pressure can overwhelm the needle valve and cause flooding. My biggest concern isn't the "how" of the flooding, it's how to manage the spill at the "when." I'm going on the assumption that it is just a matter of time before a flooding event occurs.
For what it's worth, your memory of electric fuel pump sounds matches mine.
