There's really not much to it. Install the new pump as close to the tank as you can get it, making sure the outlet side is pointing slightly up. If you get one that puts out a higher pressure than the float needled in the carb can handle, you need a regulator inline.

At the engine, just remove the old pump, and install a block-off plate. Leaving the pushrod in there won't really hurt anything.

 

Doc here, imp:

Remove the mechanical pump. Remove the rod. Install a block off plate gasket and sealer over the pump mount hole.

Install an in-line filter at the lines where you removed the pump, use gas proof sealer on the threads (if not hose type) .

Mount your Pump at or very near the Fuel tank Egress door for the pickup line and sender mount. I use an automatic transmission mount from an SBC to mount the pump on to, then mount the mount and pump on the frame/body using the tranny mount holes..this keeps the pump from "Hammering" and driving you nutz...

Cut the fuel line near the pump, using FUEL line (metal or rubber) route your lines over to the pump observing inlet/outlet orientation..Tighten and/or use thread sealer.

Run a 10 gauge wire from the fire wall are down the frame rail..on all wire and Fuel line routings BE sure they are secure, and well away from rotating parts, heat producing parts, and can not be hit by road fodder..Be sure wires can not short through the lines..Connect your 10 gauge wire to the fuel pump.

If the pump is a lo current draw under 10 amps, connect your pump wire to any switched battery source. FUSE it a 10 amps..

IF the pump draws above 10 amps, use a relay to control power to the pump from the battery, and the switched source to control the relay coil.

Make sure the pump has it's own Ground wire, and is properly bonded to the frame, by burnishing off the paint and using a star and lock washer.

can i add a question ...

will a carter electric 120 gph dead head style fuel pump reiably feed a mild small V8 on its own ?

replacing a mechanical to electric pump , how much HP gain ?

 

Besides just running the pump when the ignition is switched on, you ought to consider a circuit that shuts it off when the engine's not running (in case of an accident). When I put an electric fuel pump in one of my Corvairs, I used a Vega oil pressure sending unit, with a extra contact in it that shuts down the pump if there's no oil pressure.
