Take a look at this post - especially the first image as it has the fuel recirculation cannister you will need to make your mechanical fuel pump delete operate properly (the can with the hoses and coloured tape on it).

If you try to run a single fuel delivery to the carb, you'll lose the accelerator pump and it will end with a bad flat spot from closed throttle.



I'm guessing you meant installing a electric fuel pump on a weber carb. I will check it out.
