which fuel setup

hi, im currently swapping my 1.5 carb engine for a mk1 1.8 8v gti on twin 40's

iv changed fuel tank for a gti, now im not sure which fuel pump etc is the best to use, i have x2 facet pumps posi flow and red top with regulator.

im basically looking for advise for everything i need from tank to the carbs.

thanks
