where (unless you suggest the link above) would I buy these?
I got mine from a Boater's World store. I checked their web site and
they don't seem to carry a full selection anymore, at least not that I
could find with a quick search. Every outboard motor with a separate
tank uses some form of QD though, so as William said, most marine
places should carry them. Here's another link

Apparently more places call them "quick connects" rather than "quick
disconnects". ;-)
would any metal marine quick disconnect work ?
Mostly. They come in different flavors, (older) Mercury and OMC are
the two types I'm familiar with. There are also industrial types, but
I'd expect them to cost more. Ideally you'd want both sides of the
fitting to remain sealed when disconnected. Some simple industrial
types leave one side open.
why the need for the marine primer-bulb? (not poo-pooing it, just trying to
understand)
On most remote tanks the fuel line exits the top of the tank. Unless
your generator has an electric fuel pump, you'll need the bulb to
prime the line when you hook it up.
