Inline Electric Fuel Pump

I've done a search online here and found quite a bit of information to help me, but I am still lacking the proper interpretation of it all.

My questions are as follows:

I have an electric inline fuel pump, and to test it I brefly ran a wire direct to the battery. This caused my carb to overflow. Am I then to understand that the inline pump is putting out too great a PSI for the carb to hold?

Now the electric aspect, as I understand it, I should wire it to any 12 volt accessory wire?

Holley makes fuel regulators that will do the trick. And in my experience, regardless of what anyone says or any instructions tell you to do - put in the return line. I've got a pile of electric pumps by the shed that I burned up pumping against the regulator.

Wire it off a switched on/off relay (switch in the cab). There's many situations where it's nice to control that being on or off. Also one more step in keeping stupid people from taking your rig for a ride.

The Edge... there is no honest way to explain it because the only people who really know where it is are the ones who have gone over.

To help in the "overflow" problem, I put an in-line filter after the pump with an 5/16" return line back to the tank.
I keep the Holley fed and don't have too much pressure on the floats.
