Opinions on Electric or Manual Fuel Pumps

[JRBECK64]

I have been running an electric fuel pump on my Sons 64. It is one noisy son of a gun. Some times it sounds like its loosing its prime and then it really gets loud. What recommendations would you give as far as brands and type of Fuel Pump or would you go back to the Manual Pump? This is a 69 327 with a Slight Cam in it. I am running a 6 PSI pump in it now and is seems to be keeping up as long as it keeps its prime. I am still running the original fuel tank behind the seat if that makes any difference I did put a new Sending Unit and Gasket in it while I had the truck down for resto. Thanks for any advice you can give on this.
