whats need to add twin carbs

Hey guys. im looking at what mods are needed to add twin carbs to a car. i have a new engine being put together and it has twin dells. my current engine has a single webber. so what is needed to make sure i can hook the carbs to petrol. i already have an electric fuel pump. low pressure but high volume. so can i just t piece it and connect it up or do i need bigger fuel lines and a regulator and stuff. and if i need bigger lines how do i do it or is it easier to take it to a professional? thanks in advance for the help
