FUEL REG./ SUPERCHARGER ?s

This question is for those of you that are running a supercharger. I got all the right ignition parts i need. I have a Holley blue fuel pump. I am having trouble finding the right fuel regulator. Alot of them come with a return line port inwhich i dont need. They all also come with a vacuum line port. They say it goes to the intake for higher RPMs. Im stumped Whats your thoughts ? Thanks
