Default Fuel pump and Carburetor
I converted my crossfire to a carburetor. The recommended psi for the carburetor (edelbrock 600 cfm) is 6.5 max. Can I install a pressure regulator in line with my stock pump in the tank or do I need to convert to a micro pump?

You can install adjustable fpr to set pressure where you want.

Yes. Just make sure it's a return style regulator and utilize the factory return line.

I use a mallory 4309 regulator. Think they are owned by msd or holley, not sure. Quality unit and it is a return style.
