I went with the Clay Smith Cams mechanical pump on mine with an Aeromotive regulator plumbed in between it and the carb (which is a 1050 Dominator, and I've never had supply issues). I draw out of the tanks and through the fuel filter/water separator.

Looks like the website is down, but George was the guy to talk to when I set mine up years ago.
