    you want to run a electric pump with the carb. right?
    first you can't use the stock pump, you will need an aftermarket pump that mounts inside of the frame. you will also need a fuel presure regulator that will turn down to about 5 psi

    I just got my NEW J.C. Whitney catalog in the mail. In it, is an electric bellows pump with an internal bypass That put's out 4.5-7 psi. No regulater needed. This pump is made by Walbro. catalog # SD730907Y and is 39.99. This is the style pump I was talking about. I know Borg warner makes a similar pump. But don't have any part #'s.
    Al you need to do is mount the pump and ground 1 wire and use the power to the coil as a power lead. Tap into that wire.

    Better to connect the pump to an "Ignition Fused" spot on the fuse block.
    Some folks use a pressure switch so the pump stops when the oil pressure goes away, as a safety feature.

    I bought a carter electric pump to replace my red holley. I couldn't be happier. It's quiet and doesn't leak. Mounts inline just like the holley did so I didn't have to change anything except how I bolted it to the frame. It runs 7 psi so it works for the carb. It's their street strip model from summit.

    clicky

    Little spendy but I think its a good pump.
