I checked this morning. I have a check valve on the return line before the tank. At the moment I forget the pressure setting on the check valve.

I'm using a Aeromotive regulator on the GT40 motor which has an in and two out ports. Also a 1/8" port for the pressure gauge. This is why I need a return line from the fuel rail.

The Mallery on my Cobra has an inlet port, two supply (out) ports and a return port to return the excess fuel to the tank.

It's my understanding that you want to regulate the fuel pressure down to what is acceptable pressure for the system. In my case 40 lbs. My fuel pump pressure is a lot more than 40 PSI.

If I have a hundred PSI on the injectors I will have to much fuel. A rich condition.
