I believe that rigging up the fuel pressure gauge so that you can observe it with the car running on the road is the best way to determine if the fuel delivery system is performing as it should under actual driving conditions.

It won't tell you much of anything about the carburetor. For instance you could have a problem with the float level setting or a sticking float valve or power valve, and the fuel pressure would not reflect that.

But if the fuel pressure collapses when the car starts stumbling and dies, it points directly to an issue with the fuel delivery.
