Magnafuel Pressure Problems I just wired up my Magnafuel 625 fuel pump with a Magnafuel Quickstar regulator. I have -8 supply and return lines. My fuel pump comes on when it's supposed to, but fuel will not go past the regulator. I've taken apart the regulator and checked everything but nothing seemed out of the ordinary. The pump pushes plenty of fuel when disconnected from the regulator. Is there something I'm missing for this to work properly?

Typically, efi motors will feed the rails first, the return from the rails feeds the regulator and the regulator return is out the bottom back to the tank. Sounds like you need to replumb a bit
I googled the regulator you posted but couldn't find anything definite. I'm running a magnafuel as well. Which part number do you have?

On mine the feed line feeds into the fuel rail at the back drivers side and comes up and around into the back passenger side rail and out the hose to the side of my Magnafuel regulator and the bottom hose is my return that goes back into the tank
