fuel injector size?

[turbod]

can anyone tell me what size and how much bigger than stock is a set of "blue top" injectors? i have them on my car now and i would like to replace them with a new set. i wrote down the part number from them and it is.......762.......280150967 i dont even know who makes them? my car is all stock, do i need something bigger or smaller than these? has anyone ever heard of these? also i bought a new fuel pump and was told NOT to reinstall the pulsator is this a good idea? any help would help......thanks
