fuel filtering/polishing flow rate question

Good afternoon. New member... sorting out the mechanics of the forums. I am installing a homemade polisher. seperate loop from engine. I have a walbro 40gph pump and filter rated for same but the math of fuel supply line/flow rate is beyond me. I'm thinkin' 1/2 ID will get the job done but I prefer 3/8. Anyone have an opinion (or any rocket scientists that can manage the calculations) on whether or not 3/8" is big 'nuf? Thanks.
