It’s not the fact that it is 12 volts that is the problem. The design relies on the flow of fuel in the Venturi, creating the suck to make it all work. What you need is a pump of any voltage that delivers the correct flow of fuel through the Venturi. If the pump specs are correct, perhaps the amperage available from your 12 volt source is not enough to run the pump at the desired output.
