electronic fuel pump???

You can use any "EFI pump" with a carburetor. Indeed, they will put out much more volume flow at 5 psi than at EFI pressures. Of course, you will need a pressure regulator with return tubing to the tank, as for any positive displacement pump (gear-rotor, etc). In external pumps, there are only 3 main types I have seen - Ford V-8 type (~$50, 5/16" fittings only), Bosch type (~$60, 1/2" inlet, strange banjo fitting outlet), and Walbro type (~$100, 5/16 or 3/8" fittings). The Ford type should work fine for any carb. Just ask for an 85-95 (?) Ford truck or Mustang w/ V-8 at auto parts or check ebay. Lookup my post to see a Walbro pump on my 65 Dart and I currently have a carb on it.
