Hopefully not confuse you more. If you have not purchased your fuel delivery components yet maybe look at Vaporworx. Using Carl's controller will get you away from the old school return systems and provide reliability of a factory fuel pump and other benefits. This is the controller I am using
https://www.vaporworx.com/shop/produ...le-controller/ Picking up some more parts from him on Thursday as he is near to me. Will control the stock pump for my motor and will work with many other LS motors. Many advantages going with oem deadhead pump (especially pwm) over aftermarket return style systems.Super nice guy and is very smart. Nothing gained from recommending his company, just like him.
