For the electrics all you'll need to run is an electric petrol pump and a coil. Both need to be wired to your existing fuse box off a connection that only has power when the ignition is turned on. Make sure you wire them off a fuse that can handle 20 amps and on the side that won't have power if the fuse blows.

You don't want a high pressure pump otherwise it's going to flood your carby.
