Aeroflow fuel pumps - anyone used them?

I know there are many fuel pump options available but here's another potential that I'm considering.
Anyone out there have any experience of their external carburetter application pumps?

Looking at using a pair of them with Malpassi regulators on a 347 motor.
Range is 7 psi / 97 GPH up to 14 psi / 140 GPH.

Design works well with a Southern GT as the pump inlet can be mounted at the same level as the tank outlet - pumps are pushers.
