Adrian, when we used to race karts we used pulse pumps which would operate off the pos-neg-pos-neg pulsing of the intake tract. Unlike your carbs though, ours had no float or bowl. I would think the pump you have in mind would work fine for your application. Here are links to the type of pump we used.

Did you have to prime the fuel line initially, or would this pump do it for you? I do have a vacume line on one of my carbs that normally connects to the fuel petcock (I beleive the vacume opens up the petcock) but I'm not sure if the vacume also regulates the fuel flow, or if it's just used to open-close the petcock when the engine is running vs. not running. I'm wondering if I could power one of your pulse pumps using the petcock vacume line.

I'll try out the electric fuel pump I have tonight. It's one hell of a LOUD pump though -- it sounds like a jack hammer. They say the pump won't flood my carbs, but from the noise the pump makes (Just tested it for 1 second), it sounds like I could drive my 150 PSI air compressor with it
